I'm a virgin

I have never been kiss and I have never tried sex before and I'm 18 now. I believe in marriage before sex. But I'm currently seeing this guy he's 2 years older and he is not a virgin, we had this talk about loosing his virginity and such. I don't know with him but I think he kind of want to have sex but I told him Idk when will I be ready for that, but I'm willing to give him my first kiss tho. Please help me.
