I think it might be a good idea to have a thread where sedditors post sex advice. Pick up is important, but if you're smooth and are totally inept at sex (or even just average) it is hugely incongruous. It could cost you a lot of girls. So yeah, anything that generally works for you - or stuff to stay away from - share it.

My contribution: Never try anything new your first time with a girl. Almost every sexual fiasco I've ever had can be chalked up as being some derivative of this mistake.
