That isnt enough though,you have to choose your partners very well,it baffles me that people dont think much about this,for example I know a guy who says that he cuts the top of his condom in an cross shape,he says that the condom looks normal,but when its pushed back by friction,you know what happens.....
This guy is in top two of most promiscuous guy I ever met,for sure he has something,the guy is full of those kind of stuff,he is the top 1 liar I ever met,yet girls go crazy for him,it really baffles me,and then when I turn down girls who go after guys like him I get scorn badly,I am only trying to take care of my health and well being.
