If you have a vagina, chances are your first experience will not be that great. It takes quite a few tries for sex to stop being uncomfortable and for your brain to begin getting used to the sensations and later on even finding it enjoyable. Also, depending on your age, if you're in your teens, sex tends to become more enjoyable in your 20's, it's just biology.
Maybe you're like me and you absolutely need to feel a real connection spiritually and intellectually to feel aroused. Don't give up just yet and settle on a conclusion. There might be amazing intimacy and pleasure in your future.
