I have done this before. Probably approached like 5 girls in one night and asked them if they wanted to fuck, some laughed, some asked me, ''do you think I am a whore?'', etc Of course I didn't get any lays from saying this. You are better off approaching a girl, getting sexual for 2 minutes and then ask her to come to your crib. If she is down to fuck, she will come.
In general, girls will react better than you think, specially if you come across as a pretty confident guy.
