Guys I have a Q for you( men only please)?

I've known this guy for 2 months now. We became good friends none of us ready for a relationship so we are friends with benefit. ( I don't believe a guy uses a girl for sex specially when we both know we are not dating). Anyhow first nite we had sex we kissed for 3 min not even he though I was a good kisser and taste good. Since then we kissed uring sex like once for 2 second. I asked him last time that how much u don't kiss me he said yes I do. I said when?lol. The other nite I went for his lips during sex but he kinda pulled away. I know I don't have a bad breath I don't smoke either. He smokes. If he was grossed out by me he wouldn't spend so much time or even have sex right?even if I had bad breath he wouldn't want to be around me. Its just weird. Now he's been spending alittle bit too much time with me. Is it becuz he dosent want to feel more? Plz don't say he is using me for sex cuz I sdnt believe a girl gets used for sex when she knows what she's getting her self into.
