You don’t need to be asking the men about this, rather the women!
He is bored and wants a challenge. Stop initiating and spend some time apart. Make him work for it.
For some reason I can’t explain some women who try to often to initiate sex will put me off while others remain a turn on. I have had relationships where it felt better if I initiated and other relationships where it felt better if they initiated. My present girlfriend I have been with for close to 20 years and she has a high sex drive, I am pissed off at her a good share of the time but for some reason she always turns me on. I would suggest you back off and see how he reacts.
I doubt at that age he’d have ED (though it is possible).
Maybe he’s just not all that sexual.
Or maybe spending a bit more time apart during the day might help.
Yes, this.
I doubt if he is getting it somewhere else. The myth of the guy who is a horndog always ready, willing, and eager for sex is a myth. So is the myth that all men want sex at least some of the time. There are plenty of men who don’t.
But THIS WILL NOT GET BETTER. I promise you: he will not change. If you can’t get him interested when you’re sitting on his lap fondling his equipment, give it up. If you want a regular sex life, find someone else. Seriously.
You have two problems: not enough sex and not enough communication. Maybe you can get by having one of these problems, but both? No way. I’m with ThelmaLou, especially at age 20.
A tale of slightly titillating romantic travails or not, I’m going to second DrCube here. Performance anxiety and low (sexual) self-esteem can explain all of the boyfriend’s behavior. I remember feeling immense pressure in all the wrong areas, when faced with the task of performing with enthusiastic, initiative-taking, desirable women when I was a young, physically healthy guy. A certain level of (initial) passivity from the same women and me taking initiative, and I’d experience raging hard-ons that lasted and lasted, and powerful orgasms. No ED, no low sex drive, no cheating, no not being into you - just a sensitive guy crumbling under pressure.
I don’t know about the rest of you, but I for one am so tired of getting invested in these heart wrenching personal human stories and never getting any closure. It’s as if the OP is cat-fishing with our emotions.
Right?? I’m annoyed and all I do most of the time is read them. Just like tv shows getting cancelled without a finale :mad:
Easy solution: don’t read them.
Not read them? It’s like standing at the checkout counter at the grocery store and not reading the tabloid covers on the rack. The alternative is turning to the shelf of candy bars on the opposite side. At least the tabloids are zero calories.
Add a third problem: they spend FAR too much time together.
The reason is, as in the case of the OP, there are few happy endings.
It could be as simple as libido mismatch, which is the most likely cause. Just because he’s 20 doesn’t mean he’s necessarily a walking hard-on (life is not a sitcom/romance novel). And maybe he’s embarrassed that you’re DTF more often than he is, which is why he hasn’t addressed it.
But think about it – does the reason even matter? There’s no reason that would justify his disrespectful treatment of you. Even if he’s not in the mood, pretending not to notice is a classic passive-aggressive tactic. The real question is how long you intend to put up with the status quo. The fact that he is pretending not to notice while you’re actively seducing him would be a dealbreaker for a mentally-healthy self-sufficient woman.
You can ask him about this, have a few heart-to-hearts, and maybe things will change. But more likely, they won’t (or will change for a little while, then revert). Nobody can change their libido on command. Frankly, you’re both too young to waste time on a relationship where you’re not both on approximately the same page. If you keep looking for someone with a similar libido to yours, you will eventually find a better partner and look back at all this agonizing, wondering what the hell you were thinking to stay with him as long as you did.
Live your life in a manner that minimizes regrets. 
I’ll second (third?) depression. It sounds like the two of you moved and don’t really have a social network (yet) in the new place, so it’s each other all of the time.
Bye Bob. (battery operated boyfriend) If he doesn’t want to, date Bob. That just may get a rise out of him.
I’m not too sure how to reply to everyone on here. So for the ones who are reading this; I spoke to him about it. I let him know how I feel and he felt as though there was something wrong with him and he was apologizing, etc. I let him know it’s okay and I’m not upset but just communication and I said a few other things to make sure he didn’t feel pressure or like something was wrong with him. since the talk, we have had a VERY healthy sex life. I don’t mean to hand you all titilating information and ditch out. I appreciate all of the feedback, I just truly do not know how to work this website. And for the user who continues to be so vulgar and rude due to the fact I am new to the site and ask for information and viewers insight to what “maybe” they have experienced. I am new, however, I have read forums and have been on This website without an account for quite some time. So please do not try to judge before knowing. Another tid-bit. We both work. I was simply stating that I know his sex drive isn’t down due to over masterbation to porn; as some could assume.
You called it.
There are a lot of very cynical and suspicious people here, Whatsthis; I encourage you not to take it personally. Years from now, when you’re a long-standing and celebrated member of the board, with thousands of insightful posts to your name and a vast network of close friends, you’ll look back and laugh at all the silly skeptics who think you’re an obvious troll pulling a tedious “new poster with iffy English skills seeks relationship advice” ruse that was never funny or clever to begin with and is now so thoroughly worn into the ground that you ought to be embarrassed that this is the best you can come up with. And welcome!
