Two 'is it wrong' questions....

You like what you like. If there's a specific attribute that you prefer, then that's your preference and there's no shame in it. We all have that.
As far as reciprocation, as long as you don't BS around with it, I don't see the issue. I go to a hole to shoot my load, never to suck. If the person on the other side doesn't like that, then they should consider making it clear from the start and/or just wait until the next person.
