How you make sex?
You can't make sex, you can ask someone to have sex with you. It is possible that you are confusing "have sex" with "make love."
Sex does not always hurt. The pain that is felt is the soreness of your genitals after sex. Rough sex and prolonged sex will make your genitals sore from over working them. The more sex that is had, the more your genitals get sex to the friction and the soreness that is accompanied from having sex. Pain usually decreases when you have sex alot.
