I've never really dated but one guy who was coming on to me said in passing conversation "Well, I'm a manwhore..."
I also get guys who say things to me online, and I mean really let loose things.
Me: Sorry, I only do things with guys if they provide me with a ring in the future.
Guy: What if I wrapped my cock around your finger, will that work?
Me: *logs out of game*
Guy: Are you a chick or a 12 year old kid?
Me: I'm female.
Guy: Heeeeeey baby, a/s/l?
Me: Old enough/no thanks/somewhere you are not *logs off server*
