I've never had this problem before - well, even now it's not really a problem, but I feel bad when I do it - where I have to fake an orgasm with my girlfriend. Why? Because I'm tired of doing all the work and my girlfriend has already gotten off. I mean it's not like I do this regularly, but only when we go for like 3-4 rounds at a time. Obviously I'm going to be shooting blanks by then and it gets painful.. sometimes really painful. Just today we were on our 3rd go at it and after like 20 minutes into it she was done and I was still going. I was just getting more and more tired and I couldn't feel it ending soon for me so I thought to myself "fuck it, I got off twice already and she's had her fill so let's just cuddle" and hopped out.
So anyhow.. is it wrong that I fake it? Is it deceitful to my girlfriend? Should I feel ashamed that I have to fake it? Have any of you resorted to this before?
