I think you should ask to see his genitals for evidence of wartiness. Penis will ensue!!! Whoopee!
(It’s Leap Year Day - I get a little giddy.)
Well, it looks like I made the right choice. I told him that I wanted to wait until I knew for sure that this would be a long term, committed relationship and that I wanted to go through the vaccination process before any kind of penis ensued, which meant at least 6 months of waiting for the vaccinations alone. He seemed shocked and admitted that he had been expecting me to either break it off because it isn’t worth the risk or say that the risk was so low I didn’t care and climb into bed with him so he wasn’t sure what to think about this whole rational, adult approach to the situation. He said he had to think about it and I haven’t heard from him in a few days, which basically translates to, “I like you enough to have sex with you but not enough to wait for it.” I guess now I am single again but I am still disease free so it all worked out for the best.
If he had liked you enough after 4 dates to go 6 months without sex, I don’t think he knows how to do it. (Or get it.)
Just to respond to this part only, yes, this is something that can and does happen all the time in this day and age, even among “normal” people. 
Sounds like you made the right choice, then. I must say it’s a little bizarre to expect you to either break it off or jump right in the sack; I think your approach makes by far the most sense (sensible sex? Who’da thunk?). I guess he’s more interested in instant sex than in a long-term relationship, despite his apparent claim that he’s looking to settle down.
What a strange and dissapointing reaction on his part.
Well, it’s like I said:
Good for you.
Do you think if you haven’t heard from him for a few days that means it’s over? He might need some time to think. And you both might need a few more dates before deciding whether either of you wants to commit to six months of waiting. That is an awfully big commitment to make after a relatively short period of dating.
Heck, I pursued my wife for a year before she even agreed to go on a date with me.
We’ve now been married more than 10 years.
Exactly what I was thinking (except I spelled “disappointing” right in my head. 
) Chalk it up to a learning experience and move on, I guess.
While I’m happy for you that you made the right choice, the reaction of the guy doesn’t really surprise me at all. I’m giving him -1 if he doesn’t call you at least to briefly chat about stuff in a week, but really, what obligations did you have for one another?
