I think I got the wrong signals a few weeks after the birth of our first child. We were messing around (this is a long time ago so I am not quite sure of the circumstance) anyway, she was under the bed clothes I was on top so there were a few blankets in between. Then she changed her mind while I had got a massive hard. so I stopped in my tracks, and somehow it may have beed a good thing she said no. Because motionless I laid on her and tried to surpress an orgasm (and failed - so tried to hide it). The thing about it, that I remember most about it, that in respect for her, I felt incredibly guilty for having the orgasm. I don't think she new.
