Love can exist without sexual desire, and vice versa. Many people are happiest when both love and sexual desire are shared by both partners. Sex involves responsibility. Sex partners need to share responsibility for birth control. They should also protect each other from infections like HIV, gonorrhea, herpes, genital warts, and chlamydia.
Communication is very important.
Sex can mean different things to different people. But it is not a good substitute for conversation. Some people expect sexual intercourse to bring them closer. Sometimes, one partner is having sex just to have sex while the other expects a long-term relationship. We need to talk to our partners to be sure we are clear with each other.
