It SHOULD be a deal breaker, but some guys don't respect themselves enough to say no....So it's a personal thing. But by the 2nd date
1) I may or may not know if you can cook
2) You may still be putting up an facade as it relates to your intelligence, which is a damn important thing.
3) I definently don't know your 2 other friends and their sexual history or prowess.
4) Don't know if you swallow yet and I refuse to be wasted.
5) Don't know your general demeanor towards men and if you are respectful or not towards them.
6) Don't know if you're a gift giving girl. And gift giving women are for the motherfuc*ing win.
7) Don't know if you are adventurous enough to keep hanging out with me.

and finally, by the second date, I definitely haven't made you work hard enough for it.
But yea, I would ask him.
