Ok, here's my two cents on this issue...what gets me more interested than anything is if the online dominant can stimulate my mind as well as my body. It helps, certainly, if I can picture him next to me as I'm performing for him. It heightens the experience for me. Good looks are, as Silke said, icing on a really good cake. It takes a subtly forceful personality who can challenge my mind to get my motor revving, rather than some Adonis who knows he's good looking and completely vapid. And if that person is a really nice person, but a total slob...no. Friends, yes, but anything more...it speaks volumes of their self-confidence. I'm rambling now...sorry. Hope this wasn't too confusing.
