[*]How do you feel about your partner's breasts?
My partner has had top surgery, but before the surgery I didn't feel any way about his breasts, they were just there.
[*]Are they a turn on or not?
Not a turn on
[*]Do you want to touch them? Ignore them? Play with them?
I didn't ignore them, they just didn't exist as breasts. Even if I saw them they I made no mental connection that they were breasts. Sounds strange I know, but it's the truth.
[*]Do binding vests turn you on?
Nope just another piece of clothing like socks. (which don't turn me on)
[*]If your partner had top surgery, would they become more or less attractive to you?
The chest being flat is physically attractive to me but what really is the turn on how he finally feels happy with his body. That extra self confidence (because we all know he wasn't lacking any to begin with 
) is pretty hot.
