Why is it after an intense do I become ticklish and limp? This is a problem that my boyfriend has not. ?

Well I'm 26 and have a few medications I am currently on and some do have ual side effects and I know now how to deal but the ticklish and limp has been since I was 1st ually active. My partner seems to think it's something I can get past but it brings me to the point of laughter and the sensation of having to pee. Either me nor him would want that to happen but it feels that it will. And he longs to continue orally pleasuring after I . And I seem to not be Abel to remain hard nor keep from squirming around and laughing. He thinks it's due to me not being attracted to him. Which I so am. He is the best lover I ever had in my life. But I'm at that time where I have no answers and I feel bad and it sometimes turns to anger. Please tell me there is a reason for this to help me keep my lover happy and tips to maybe find things I can take or ask my doctor about to make him feel better and me at the same time I know it's not him it's me. It has been this way since I was younger. Are there things to help with maintaining and having multiple 's. I really don't want to looses a relationship with the one I love over a ticklish . LoL no I want a stronger more intense drive and life.
