I Need Help With This!?

So This Is The Story. Some months ago I Met this guy (new in my school) and i hated him. Three weeks ago we went to a medical brigade and well we started talkin and all that. Back to school he started like talking to me and all that and chattin with me on facebook(thing he never did before the brigade) so a week ago our conversations turned from friendly convs. to sexual ones. Now, what happened two days ago left me confused. My class had a skip day and we went to the beach, so this guy told me to go with him another place (a lonely pool) and he started like touchin me & all that so i left the pool cus i didnt know what to do. I really like this guy now, but i dont know if he likes me or maybe just wants to play with me (sexually or i dont know what) SIGH. I Need help.
