First off I’m bisexual. I have an issue and I feel embarrassed to say it. I’ve not been able to cum lately when I have sex with guys. These have mostly been hookups. It seems to take so long to cum that I end up getting frustrated and so does he. I’m not sure if it’s because I already jerked off that morning, or I’m not really into the guys I’ve met. I feel very attracted to them, so I’m not sure? Has anyone else experienced this?
