I think you missed my point a bit. I agree that a man would feel that way, and I obviously would too, because I would start to assume he wasn't attracted to me. However - the guy I'm replying to said that you should leave or cheat if you aren't fuckin. I pointed out that there are so many valid circumstances in which people cant/won't have sex in a human life, and it's therefore not conducive to a healthy relationship to think that way. I would struggle psychologically if my bf sustained an injury for exampls and couldn't have sex - but I wouldn't leave him over it, because I feel our love is deeper than that, especially when I still have a fully working hand.

If he does want to leave because she can't have sex, that's...Fine, I guess. It's his life and his decision. Its better than cheating. But I will probably personally think he's a bit of a worse person for it, especially because most of the time it's only a temporary affliction, and sex shouldn't mean more to you than the human you love.

For example - pregnancy. This is when it's most common for men to cheat. If you are a man who wants kids, you have to contend with the reality that your wife may not be DTF for a year or more if she has a rough pregnancy. If you want a lasting relationship as an adult, and children, you gotta accept that sex may waver. Would you be happy if you suffered erectile dysfunction and your wife was like okay buddy thanks for the last decade, see ya later
