of sex until you reach 60 years old!!! Without any religious clout, I personally believe there is a huge difference between casual sex and serious sex. And sex has its consequences; it is a two-edge sword. It is a human nature to satisfy your sexual desires; meanwhile, you have feeling to go with the desire which differantiate human with animals.
All in all, don't get yourself hurt or hurt someone during 活塞运动！！
