Does anyone else have to tense their leg muscles to orgasm?

Ever since I can remember, I have always had to tense my leg muscles (my legs have to be out straight) in order to orgasm by clitoral stimulation (rubbing really hard and fast). I don’t think I have orgasmed through intercourse more than a handful of times in my life and I am in my 40s. I have always thought there is something wrong with me. I was sexually abused as a child and I wonder if that has anything to do with how I orgasm.

Hoping I am not too abnormal.
