On the average, about every other time we have full PIV sex. Maybe 4 or more times a week. It depends. I had to turn him down while I was recovering from the UTI I just had, he knew I couldn't have oral or PIV sex, but thought maybe.... but it was too close to the parts that hurt from the UTI. Plus, I reminded him had had to have an orgasm before we have anal and there was no way to give me an orgasm for the entire week I was recovering. Stuff was just too painful, and I shouldn't be touched while I was healing. He understood completely, felt bad about asking, and he got blow jobs instead.
I'm feeling better so we're back to the fun. We slowly eased into it last night.
