How to find an occasion to show my penis to girls?

hmmm,when you are at sea or at a swimming pool,you can deliberately pretend that your swimming suit is washed off and if the girls didn't notice,either you willy is not big enough or you should do it multiple times to make it seen.good luck with that.

girls？你有几个？看你们关系发展的程度以及女孩对这种事情的态度，可通过日常的交往观察她的态度
