Should I let him or not

only you know what you want and what your motives are. if you decide to have sex is it because:you want him not to leave you and you don't want to be labelled as "frigid" OR is it because you want to as well but are a bit scared? figure that our first, maybe do other sexual stuff to get comfortable, but ALWAYS BE SAFE. do not compromise your values, if your not ready, your not ready.if you are you are.

Listen to Katie. She is 100% right! Don't just "let him"

It is normal to be nervous. I would ask you if you really want to do it. Seventeen is pretty young to have intercourse and you may not be emotionally ready for it. There are also other things you can do besides intercourse such as petting, oral, kissing, etc.

It sounds from the way you word your question that he is trying to convince you about something against your will. If that is the case then I would say you probably aren't ready for intercourse.

Regardless of whether you engage in intercourse or not you should have a discussion with him about it. Find out what it will mean for each of you. What happens if you get pregnant? How would you deal with that? What does it mean for your relationship? These are all things you should know in any relationship, but we often just assume we know the answer to it.

Katie gave you a good answer. I gave her a thumbs up. The title of your question said it for me. "Let Him" tells me you are considering doing something you don't want to do. If you don't want to do it, it isn't time yet.

By the way you pose your question it sounds to me like you are thinking of doing it only for him. Your virginity is something you will never get back, it is like a gift to be given freely you should not be pushed or guilted into giving it up, It sounds to me like you don't feel quite ready yet. If you are at all worried or nervous don't do it, it's supposed to be something that makes you feel good, it should be something your are sure of. If the young man in question really wants to be with you he will be willing to wait a little longer until you feel comfortable with it, if not he wasn't worth giving it to in the first place and you will be glad you waited. There are many other things you can do without have intercourse if you feel like you want to be sexually active but do not want to give up your virginity. Do not allow yourself to be pressured into something you may not be ready for. Having sex for the first time is something that can be very emotional for girls, and if the boy does not understand that, your going to get hurt. Whenever you do decide to do it make sure you are protected, condoms are given away in most planned parenthood clinic's.

NO, NO, NO! You just gave your own answer "HE IS TRYING" . Nothing in your statement about "I'VE BEEN THINKING ABOUT"! You are both very young for this and especially in your case you will know inside, in your heart when you are ready to do this. It is and will always be a special moment, don't ruin that. It is the boyfriend all the way that wants the sex, tell him NO and if you loose him, you have just found out what you had! NOTHING If he really cares for you and respects you and your decisions he will whine a bit, but will hang in there with you!
Hope this helps
