I enjoy doggystyle.. but not if my partner is too big and hits my cervix too hard. That is, unfortunately, an issue with my current boyfriend. If he doesn't tease me mercilessly before any sex, it takes a bit of time for me to be able to take all of him. And he likes to go in deep. SIGH.
However, during that lovely ovulation time of the month when I'm constantly ready to jump him (like Sunday, whoooo), he can go as deep as he wants because I'm already super duper aroused. Lots of fun. Sort of makes me wish ovulation came more often than once a month.
Also note: doggystyle gives you a pretty good opportunity to reach around and give her breasts and clitoris some nice treatment with a finger or two that were, perhaps, recently lubed up by making a pass around her vulva. Encouraging her to do some of this pleasurable work herself may also help.
