Love and sex are NOT the same thing. Love is an emotion or a feeling. There is no one definition of love because the word “love” can mean many different things to many different people. Sex, on the other hand, is a biological event. Even though there are different kinds of sex, most sexual acts have certain things in common. Sex may or may not include penetration.
Differences Between Love and Sex
Love:
Love is a feeling (emotional).
There is no exact “right” definition of love for everybody.
Love involves feelings of romance and/or attraction.
Sex:
Sex is an event or act (physical).
There are different kinds of sex but all kinds of sex have some things in common.
Can happen between a male and a female, between two females, between two males, or by one’s self (masturbation).
Ways to express love without sex
There are countless nonsexual ways to show someone you love them. You can show a person you care for them by spending time with them. Go to the movies. Or just hang out and talk. If you are with someone you really like, then anything can be fun.
There are also ways to feel physically close without having sex. These include everything from kissing and hugging to touching and petting each other. Just remember that if you’re not careful these activities can lead to sex. Plan beforehand just how far you want to go, and stick to your limits. It can be difficult to say “No” and mean it when things get hot and heavy.
