Any Advice?

Alright so my best friend came over the other night and everything and we can pretty much entertain ourselves well i had just finished watching Insidious and then we went for a walk on the gravel road in the pitch dark. Biiigggg Mistake i was so freaked out i kept looking behind me and totally got myself creeped out and im the kind of girl who loves scary movies and all things paranormal but man i was creeped lol. So lately this guy ive been sorta friends with for a while and everything is dating like crazy but he only talks about sex with me and he knows how i feel about it and everything but it seems like he doesnt care hes always askin if i would let him take my v-card but truth is i dont want him to but he kind of pressures me i like him but i guess he only wants sex from me, just today hes tellin me to masturbate and think about him and when i say no he persists why cant guys ever take no for an answer? i dont do anything to look slutty because im not im just myself and apparently im a tease?? i dont see how one guy even told me my eyes told him i was beggin for him to have sex with me but i dont ever realize any of this?? Any Advice for me?
