You know what they say about women in their thirties...my wife and I have been married for 11 years and in the last year, she has become so much more dominant and aggressive during sex. She has a black belt in Tae Kwon Do and does a lot of yoga, so she has become physically strong (probably stronger than I am). Her legs in particular are long and have a lot of power; all those martial arts kicks have given her wicked hip and thigh strength. Now, while we are having sex she'll wrap her legs around my torso and squeeze with amazing pressure. In the past, her leg grips were applied lovingly, now she likes to threaten me with those legs because she knows she has so much power over me. I like it a little slower and easier, but she insists on deep and really hard. If I am not doing her properly, the next thing I know I am trapped between those rock-hard thighs and getting scissored until my ribs ache with pain. My wife is then taunting me, demanding that she be fucked hard or else she'll crush me harder with her thighs. She has learned not to link her feet too low behind my back because then I can't move in and out. So she wraps me up higher on my chest so I can continue to pump, but the pressure feels so much worse. I used to sort of enjoy it, but our sex is becoming more of a workout (and my ribs are always sore the next day). I don't know what to make of it.
