Question about sexual reaction

Hi, I didn't know where to put this so sorry if it isn't in the correct forum page.

So first of all, I'm a bisexual male with a bisexual boyfriend. We have a healthy relationship with each other.

I've discovered in the last few months that we've done sexual activity that the feeling of pleasure I receive is either delayed and only appears when I'm not with my boyfriend or is negated completely during those sessions. Earlier we tried anal sex for the first time. I was the more male between me and my boyfriend, but unfortunately he still had shit in the immediate area of the anus so I couldn't or didn't want to fuck him. Me however, I didn't have any shit as I've released it earlier so we came to a conclusion that he should try it on me. I expected to feel a lot of pleasure but all I felt was something like shitting. I noticed it wasn't the first time to happen. He sucks my dick, I feel normal. He gives me a handjob, normal. He touches my erogenous spots... Normal. But the weird thing about this is that my body reacts accordingly, I cum, I get hotter and all that stuff but I don't feel the pleasure. Why am I unable to feel pleasure when I'm with him? I'm only able to feel it when I'm by myself.

 

??? You cum......but dont feel the pleasure? huh?

I think maybe you need to clarify what you mean by pleasure, I think maybe you are not talking about the physical there

 

Yeah, it isn't physical. It's the emotional, or... mental portion. I suppose?
