Vaginal feels like something is filling me up inside, but not unpleasantly. I, too, love that first moment of entry... especially if I'm good and wet, or lubed up. It is soooo nice to have my ktspktsp

inside me. There's nothing really to compare it with... it's just nice to have a part of someone else inside me, where he fits very nicely.
On the other hand, we've tried anal a few times and I have to admit, it's not too pleasant for me. And I wanted to enjoy it, believe me! But it really just feels like I have a big log stuck in my asshole, and I don't really get any nice sensations out of it. I also don't feel as intimate with my bf as I do during vaginal, since we're trying so hard to be careful, etc., instead of just giving ourselves in the passion and movement of vaginal.
Now, I love being rimmed and tongue-fucked, and my bf likes receiving anal himself, but I really prefer vaginal to anal. That hole is made for a penis!
