I know a lot of girls who say that the penetration part is totally over-rated. "What is it then? Just in and out and in and out. Not very exciting." For me, watching porn, it's the part that turns me on the most. In bed, when he first goes in its the best. It's like my body gets shocked, "OH GOD he's IN me" and it sends shivers through me.
Depending on my mood I love to be penitrated or I don't. If I'm really hot and horny I love it so much. I crave it, need it. To feel the slippery pressure, to be full. But if I'm not so horny I'd like anything but. I might still be in the mood, but just not wanting penitration. Thats usually when his dick finds a place in a different orifice
