Can You Give Me Some Tips?

I Met A New Guy And Have Been Talking To Him For A Week Or So And Went And Hung Out A Couple Of Days Ago And Nothing Happened We Slept In The Same Bed But We Didn't Do Anything And I Was Happy About That.2morrow I Am Going Over To Stay The Night and I am excited /nervous about the whole thing.. I mean how is the sex going to be is it going to be different with us in a good way or bad way like him not talking to me as much . I need advice on how to not be so freaked out about it! I mean I have done this kind of thing before lol but I really am wanting more out of the relationship I want it to last you know turn into something besides sex.
