How do I tell him I dont want to get involve sexually?

I’ve known this guy for about a month now, and we’ve hitted it on since the day we saw each other. We just clicked and according to all of my friends we flirt a lot. We both just got out of a relationship, a serious one and he was with his ex for a year and 6 months and I was with mine for a year and 9 months. We didnt know each other then when me and my ex broke up and when we started talking they already broke up.

Anyway we both already have said we like each other, and we’ve kissed and went to the cinema together twice and we talk everyday (If I do have credits to text him) He has told me the first time we kissed that he just want to have some time to get over his ex to get involve with someone and so did I, its been nearly 2 weeks and we kissed again.

We went to the beach a few days ago and I wore a bikini and ever since he came onto me sexually… were not together but were not really friends… I dont want to fall into that category where were just friends with benifits cause I really like him and if we do, Im sure im gonna develope feelings for him and I’ll just end up getting hurt. His a very nice, sweet, caring, hard working guy, and he always spoils me. And according to my friends he only seems happy to be with me and beside me but when im not he always looks down.

Im just getting confused with what he wants me to be. But im sure that I dont want to be just friends with benifits. I want more than that. Im afraid that if we do get it going from a kiss and you know where to… im afraid thats all were going to be. His just a guy friend we had fun with thats it. He doesnt seem that kind of person but parts of him which he only shows to me makes me think twice. What should I do?
