I did read somewhere once that it is nomal for an erection to wax/wane at times during IC. When we were dating H said that the key to "keeping him in the game" is lots of movement. I have found that what helps him is tightening my PC muscles - usually will bring things around quickly. These fixes have led to an emphasis on IC rather than sexual frills. I must admit I do like both and I get stronger o's with penetration. However, I was trying to answer Dom's question as to whether I could figure out how to be fulfilled in a sexual R without much (maybe without any) penetration and I'm sure I could work that out.
Active, engaged partnership in the sexual arena is the only "must have". My H could diddle away for hours and I wouldn't come if I had to ask 10 times and he did it while watching a football game. The sexuality in our M just doesn't seem to be one where choices are presentrd - IC or oral? Not today, how about tomorrow? Instead it is only when some kind of magic occurs where H is feeling actively engaged with life, rested etc..then it doesn't seem that his erection is an issue. It also isn't an issue if we are trying to have a baby or if I am performing oral. I realize that all of this merely suggests the presence of psychological rather than physiological factors. Great.
