My ex sometimes swallowed, but more for a favour to me as she didn't like to swallow.

But, I am with you, if you both love eachother and want to please eachother in the bedroom there isn't anything wrong, demeaning or slutty about it.

Just a few friends, when I tell them, think it is disgusting to get your gf to do that stuff.
They think I am weird for it, but I think it is them who are weird!
