My boyfriend wants to have sex but i’m a virgin

So, i am 18 and my boyfriend is a couple years older than me. We have been talking since the end of August and started dating months after then. I am a virgin and he is not so he’s horny all the time, especially when he’s with me but i just refuse to lose my V card. Everytime i’m with him, i be wanting to just lose it to him but i always stop myself because i just don’t want to lose it that easy. I want to be SURE i am doing the right thing. Although i don’t have sex with him, i try to find a way to give him pleasure by giving him head and letting him rub his dick on my pussy. But i wanna do more than that so bad... but i just don’t know what’s the smart thing for me to do. HELP!
