Only thing I can tell you is be yourself. The only time a "pickup line" works is if the girl is either mentally handicapped or extremely drunk. Either way that's fucked up. I recommend learning how to be more comfortable around women, learning how to listen and keep a convo going and having a big dick. Always works for me. Sure it might take some effort but banging the caliber of ladies I bang makes it an almost requirement. Pretty girls have heard it all, be different.
