Well I dont really pay much attention to what a person looks like. I pay more attention to the persons personality because that's what gets int he way if its really shitty when working together.

A person can not help the way the look like but they sure as hell can help their sour personalities. If that's the case.

So really I wouldn't feel any nastier or dirtier about fucking soemoen that others may find a guy less attractive than another. In fact I don't necessarily feel nasty or dirty to begin with. I enjoy it so why would I feel like that?
