No contast for me - vaginal.
Why - first because it feels absolutely fantastic (words can't begin to describe how good it feels), and also because of the overtones of intimacy and of - dare I say it? - possessing the woman and making her "mine" - even if only while the sex itself lasts.
Oral is lovely, of course, especially in the context of vaginal sex as well. But oral sex by itself leaves me happy but strangely unsatisfied.
Not really into anal sex, but I seem to be in a minority there!
Which do you like best, kwenklown?
