There are many kinds of love, and lots of ways to express love and affection for another person. Love between parents and children, brothers and sisters, love between friends, and romantic love are some of the kinds of love. Talking, smiling, kissing, hugging and touching are ways of expressing affection.
Sexual activity is one of the ways that people can show romantic love for each other.
All human beings are sexual creatures who need to touch and be touched and express affection. However, showing love does not have to result in sexual activity, and having sex with someone doesn't necessarily mean that he or she will fall in love with you. Love does not equal sex. The act of penile - vaginal intercourse involves insertion of a man's erect penis into a woman's vagina and rhythmic movements which heighten sexual excitement until orgasm occurs. The organ of maximum sexual pleasure in males is the penis, particularly the head of the penis.
