I agree with the above post, don't beat yourself up for it and just accept it and try to enjoy fully, in my opinion.... I have fantasies about being a child and being pressured by adult men into doing it. Not sure exactly why, although I have some idea, and I'd kinda like to keep it private (but something has happened to me in the past). I'm in a great relationship and for a while it's been bugging me that I can't focus as well on fantasizing about him while doing it... but then I have to remind myself that there's no use to put extra unnecessary guilt on myself since those thoughts do not linger past the self pleasuring act. Once I'm done they're out of my mind. At least I am able to have a good time - what I think about during the act is quite trivial.
