First I'd like to say thank you for helping me to discover and experiment with my sexuality, your website has been a great help to me.
My question is about one particular position, I usually hear it referred to as doggy style, I am on my hands and knees and he is behind me, usually standing on the floor while I’m on the bed. The last two times I’ve done this position it’s been uncomfortable, like he’s going too deep. My guess is that he’s hitting my cervix. What I find interesting is that when we did this position a few weeks ago I enjoyed it a lot so why is it uncomfortable now? I had a past partner with a HUGE penis and doggy style was painful so we stuck with other positions but this guy’s penis is very average, not too small but not too big.
