Sorry but I just had to add this-
It sounds like you are pretty inexperiened with sex, so I am just assuming your boyfriend is also. In that case, he's probably going to love it regardless of what you do. Young men are like that.

And the two of you can learn together what pleases both of you, the biggest tip is just to talk about it and not be afraid to tell each other what feels good and what doesn't.
If you are looking for more, there is a lot of instructional information on the internet about sex. Be careful when looking for it though, because some sites are dangerous (meaning they will give you viruses or something) but if you never download anything or give out personal info, you should be fine. Some sites are very good.
