Well I for one have been always fascinated with tits, breasts cleavage and bra's............ That's what turns me on. And there is nothing nicer than the soft sensuous touch of breast s against ones one penis and two testicles. Just to lie there and let the lady rub her breasts is really most enjoyable.
Similarly for her to rub her breasts over my face and eye sockets feels extremely good.
The remainder matters somewhat less.
