[Korean Baby Doll!]

hi! yesterday me and my boyfriend hanged out and he walked me home and outside of my apartment we were kissing and he confessed something to me he said "quiero hacerte el amor" he said he wanted to make love to me... at first i thought he was joking and then he was like im not joking... i think i made him feel bad because i didnt believe him and i didnt want to look at him or talk to him... i wanted to ignore what he had said... and he said dont you want to too? and he said i thought you wanted too... but i do but not that soon we havent been together that long its going to be three months in two weeks... i told him that i didnt want to have sex because it was too soon... he is 18 and im 17 i didnt expect him to say that at all... why would he say that? he hasnt even seen me naked or anything we have only made out nothing more..... and he said well i think its time to do something else besides make out.. and he also said he didnt want me to tell anyone help? my boyfriend is sweet respectful funny and kind... he is not a jerk that just dates girls for sex so i dont know why he told me this......help???
