Seconded. When I became sexually active they only offered the standard, old style, thick condom in the size I required, so I formed a poor opinion of them. With the advent of the newer, thin walled ones that transmit body heat I’m more amenable to using them.
I’d love it if they could make one I could feel something through.
If I were female, still attracted to women, and had a partner that wanted me to wear a strap-on because it felt good to her, I’d do so. So I do participate and therefore would not call it a dealbreaker. But I don’t get much more out of it directly than I would with a strap-on.
I would not refuse to wear a condom for a one-nighter, or a new relationship. But I won’t wear a condom in a long-term relationship. I’m not a big-dick-having guy, but condoms, even Trojan Magnums, hurt the base of my penis. We’d have to work something out once we knew each other well enough.

Female: no sex without a condom unless we’re in a monogamous relationship and I’m on birth control.
If I’m in a new relationship, I require a dude to cover it up. Since I’m monogamous and on the pill, though, the BF and I haven’t used them in awhile.
Male: I prefer it without, but it’s honestly not a big deal. My SO occasionally requests one, and I go along. It does mildly reduce the sensation, but that reduction usually translates into better stamina for me, so I don’t mind it much.
Guy. Not only do I not mind condoms, but they are an absolute deal-breaker for me. I don’t even particularly understand the claims of notable reduced sensitivity, TBH–it’s never been enough to bother me.
Granted, I have had experiences with ill-fitting condoms that were annoying to use, but that was on a per-brand basis (and seemed more prone to happen with polyurethane condoms when I was dating someone with a latex allergy).
Two things: 1. there are now johnnies have a ‘pouch’ over the glans - e.g Inspiral - that are really good and get 99% there, so I withdraw one part of my complaint; however 2. I occasionally find stopping to locate one/open the damn packet/put it on, a bit of a passion killer.
I wonder if that might be a cut/uncut thing? I’m uncut and the use of a standard condom for me is dramatically different to bareback.
There’s a whole lot more than a piece of latex that deters me from wanting to have sex with a woman. 
Or he is. Or both 
Male here, not a deterrent at all for me, I’m just grateful to be given the opportunity.

I have a strong aversion to condoms. It’s not just the insulation and barrier to any sort of tactile sensation - it’s the taste, which pretty much rules out cunnilingus after penetration and throws a pall over the whole show.
That said, this aversion has manifested as an eagerness to get to the whole “testing and monogamy” stage of a relationship. As crappy as condoms are, I’m very grateful to them for getting me through decades of casual sex without contracting any STDs.
Ya’ know. I’ve been with close to 60 women. (I feel I can throw that number out there with impunity as that number is pretty low according to some Doper’s standards.)
Only, one out of 60 has ever required that I put on a condom. Which is strange because it seems to contradict the over all animus of what this thread and other threads like this thread seem to say.
Not only have they not required it but it was never even discussed. This demographic of women ranges from college education career minded women to the drunken bar fly who doesn’t sustain gainful employment.
But no. I will not wear a condom. I’d rather jack off instead.
Still disease free according to my last blood work up.
I will only have condomless sex with a man if I am prepared to have his child should an accident occur. I’ve had too many friends get pregnant on birth control pills to trust them 100%.
The first time I had unprotected sex was my wedding night. All other times before then a condom was a given. If I were single today it’d still be a dealbreaker.
You need better logistical planning, then! 
Might be. I’m cut, but I honestly don’t see what I’m missing, let’s put it that way.
I never have erectile difficulties - unless I have to use a condom. I don’t know if I’ve been buying the wrong size or what, but it’s not easy for me to maintain an erection while using them. They seem awfully tight, and the sensitivity IS greatly reduced (I’m circumcised, in case anyone is tallying the difference in condom tolerance).
As a result, I never slept around, preferring to have long-term monogamous relationships. I prefer them anyway, but I might have had some one-night-stands in-between relationships if condoms didn’t make it more trouble than it’s worth.
