So this has been happening for about two weeks where when we’re just about to have sex and he’s in position and all hard then suddenly he goes soft?

I don’t understand because he’s so into it and wants sex but his penis starts going soft just when he’s about to go in after he’s been hard during foreplay.

It’s sort of frustrating for the both of us and it’s starting to make him feel really bad about himself but I really don’t mind and know that it’s not entirely his fault.

He doesn’t watch porn or anything and he only orgasms when we have sex (mostly blowjobs now)

I’m just wondering if this has ever happened to you or if you have any advice
