Just to clarify, I wasn't suggesting that the guy's insistence on not using condoms was a tenable position, or that WUW didn't do the right thing in dumping him. It sounds like she did.
But think about it: one thing we know about men is that in most circumstances, they'll do pretty much anything for a shag. WUW has told us that she and he "fancied the pants off each other". So he had every possible motivation and opportunity to shag her. If faced with the choice between shagging her with a condom, and having her leave him so he never gets to shag her at all, and if condoms were really not that big a deal physically FOR HIM, don't you think he would have come round in the end and agreed to use them?
It's not like he's got anything out of this, other than being dumped and not getting to shag someone he really fancied. So he clearly made the decision, for himself, that condoms do make sex either so unpleasurable, or physically impossible, that it's not even worth pursuing such an opportunity if he has to use one.
That doesn't sound like petulance or selfishness; it sounds like a simple cost:benefit analysis about how sex with condoms is to him - ie not worth doing. Nobody's going to follow up a sexual relationship if they're, fundamentally, not going to enjoy it.
He's the only one who can make that decision as it's his dick we're talking about. All I'm saying is that there ARE some men for whom a condom ruins things to that degree.
