Everybody's doing it. Masturbation is one of the safest sexual activities. A girl can't get pregnant before she turns 16. Most sexually transmitted infections happen to women and men under 25. When anyone forces a friend or a date to have sexual intercourse, it is rape.
Most women have orgasms from vaginal stimulation.
Sex before marriage makes for success in marriage. Pleasing your partner when you have sex is more important than pleasing yourself. Sex is better with alcohol or drugs. Anybody can buy condoms in drugstores or from vending machines. They are often free at Planned Parenthood health centers, other family planning clinics, and most public health departments.
