If you have doubts, you’re not ready. Don’t worry about it, either. It’ll happen. It’s not like you’re gonna miss out on something and you’ll never have a chance again. When you really want to, then you’ll do it. However, it will not go well for you if you feel like you’re being pressured.
As to being in love… most of us know that feeling. For most people who feel it at a young age, such as fifteen, it won’t be the last person you have that feeling with. A few people do enter into relationships at fifteen, and they last for the rest of your life, but not very many.
For most of us, that first love did not survive the changes we went through—high school, college, work, etc, etc. If I were you, I would be aware that even though you feel so strongly right now, it might not last for very long. I wouldn’t count on it being a lasting relationship until you’ve been together a few years, and you’ve stuck together through some pretty serious problems. If you can do that, it might be the real thing.
The same thing goes for sex. Sex can be a fun, experimental thing. It can be an expression of love. It can also get you pregnant by accident and change your life in ways you really weren’t hoping for. Sex with love is the best, and even though your love may not last, the best time to add sex to the mix is while you are in love; not because you just want to get rid of your virginity, or because you want to shut your boyfriend up.
Fifteen sounds young, but I know so many kids have started much younger—some because they wanted to, and others because they were manipulated or even forced into it. Love-making releases powerful emotions, and your love will feel even more incredible when you make love! However, that’s not just because of your feelings about your guy, it’s also because our bodies are made to have these powerful feelings, so we can reproduce.
I think that it’s fine to wait until you are absolutely raring to go. If you have any doubts or reservations, then wait. Your moment will come. You can prepare for it by doing other things besides intercourse. Maybe you’ve already done that. But take your time. Explore each other’s bodies. Learn to give each other orgasms. You can do this in any number of ways before you have actual intercourse. Just take it slow, and learn a lot, and you’ll both be happy.
