I guess women tend to be more attracted to sensuality than their masculine counterpart. Still, it's nice to find a man who loves to cuddle as much as I do.
While a big portion of sexuality is obviously the actual coitus, I am definitely turned on by a gentle touch, a light kiss on the back of my hand, a little nibble on the soft spot on my neck, a nice carress on my hip... I get goosebumps quite easily and my pussy gets wet just as easily.
And sharing all that with The Boyfriend and a common female friend in a delightful afternoon is innocently naughty. Much more erotic in my mind than an actual threesome would be.
