why do guys only see me as some one to have sex with ?

[Jess]

honestly im not a slut or have a reputation for it. But the problem seems to be that every guy I end up talking to or dating its all about sex !! I dont know what im doing wrong and every guy seems to have a girlfriend but they want to get with me .. im nothing special why cant i just have a normal relationship it sucks , yes im in high school and i bet that has a lot to do with maturity level during this age but its every guy even the so called "nice ones" .. and i just need advice or tips or SOMETHING to help me out on coming off as some one who dont want the whole friends with benefits but a relationship .. i just need a little help here
