[NSFW] I don't seem to enjoy sex with others

A bit of remorse as well... Ive notice I don't really enjoy sex with other (men). I have a hard time getting well... hard and have to get myself hard multiple times , not so much cumming once I do get hard. I never seem to be in sync with the other person.It could be because it's been mostly and mainly hook ups. I do personally, have a bit of a emotional barrier. Or I just don't have any feelings and it's just sex. Not that I've ever really done it with anyone I've actually had emotional attachment to...On the other hand I have a better/funner time with myself /a dildo.
