All Kitties are beautiful.
Just like the Penis'.

Different sizes and shapes, but, the idea is the same: It is attached to a human, who is in no control of how "it" looks.

I prefer ladies, vulvas, that gave birth. Vaginal lips are often bigger and more sensitive, which requires attention to be payed to ALL Vagina and not just clitories.
Younger ladies, who did not give birth yet, have tiny labia, which looks very picturesque. I like them too.

By, the way, why is it such a big deal when guys touch pennis'? Or look at other penis? Are you afraid, that this will make you gay? And why we girls are not afraid to touch another pussy?! Are we already gay?! Or our threshold for gayness is more acceptable?

MFM is nice. I don't have to talk. Or think.
FMF is nicer! I have someone to share my thoughts with and kiss male/female at the same time and it is just more variety right there. I like it also, because I can slack-off!
