I know there's more to life than sex, but would you be able to long-term date a guy who has some sex issues? He either avoids it by saying he's tired, has had several very premature climax episodes, avoids talking about it, and when he finally does have sex with you, it's very vanilla.

Surely this must be one of the reasons why this guy I'm talking about has never had a relationship last longer than 3 months?
