How do I let my boyfriend know I'm ready for sex?

How long have you been going out? This is just my opinion, but "fairly new" doesn't sound like you've been going out for that long, and in my experience, sex in a relationship can be very risky, especially if it's too early. It will either pull your relationship to greater heights, or it will sink very rapidly. But this is your life, you're an adult who can make your own decisions-- so if what you are saying is that you are ready for it ASAP, and you TRULY feel like you're ready and it won't damage the relationship, then here's what I have to say.

If he's like how you describe (one that respects what you desire), then he isn't going to make the first move because he's holding up his end of the bargain in response to your request to postpone sex. So you are right in thinking that you have to speak up/make the first move.

If you choose to tell him: You need to make sure he's ready too. Do that first. Then, If you can tell him you aren't ready in the first place, then surely you can talk to him again and inform him that you're ready now. From there, now that both of you are aware, you can then properly plan it together and try to make it the best night with each other thus far (communication is important, remember that... not only can you dodge many bullets using communication, you can also bring about good, memorable things- maybe you'll plan to have candles lit, or have a certain kind of music of your choice playing.)

If the element of surprise is what you seek to let him know you're ready, then you will have to be the one to "initiate things" if you know what I mean. Lots of methods can do so, but a couple suggestions are: 1) make hand contact on his thighs and slowly move.. to "other places". 2) Straddle his hips and kiss. 3) Mix these two, try other things and mix them in as well. 4) What would get you going? Whatever does, will most likely work on him. Both genders are more similar in this situation than some people think. Remember though, make sure he is going to welcome it. That's why I would suggest the first method unless you already know he's ready (in that case, either will work fine). It's up to you.

Tell him before the trip. Just let him know that now that you have spent more time with him you feel ready to have sex.

You don't tell him with words, you tell him with your actions. Make out with him, touch his bare body, and his thiing, from the outside, and just look him in the eye and say 'make love to me' . I'm sure he wouldn't object.

His "thing" is called a "penis" by the way and please please if this is what you are planning take condoms yourself do not rely on him to do so.

Have a good time!
