My boyfriend just said he wants to have sex with me tonight?

I posted a question about how he was 45 and i am 21. We have had sex before, but I'm not sure im ready for tonight. He's 7'0 really really tall and big. He's really sweet and smooth during sex though. We have only had sex once and it was my first time, so he didnt go to hard or fast. We love each other. He asked me if i was ready to have a baby and i said no and he said okay. I want to have sex with him. But i have no idea what to do. He likes to be on top, which means he's in control. Which i have no issue with. He let me take control the first time. He called me earlier and asked if i was okay because when he was texting me i texted weird because i was nervous. I said for him to come over. We talked about it and i asked him what he liked. He said anything on you baby. He's really sweet. So i looked up online how to make my man enjoy sex. They said shave everywhere, which is a must. To put lots of lotion on. And dress sexy. So help me please, any ideas what i should do so i can enjoy it, as I can aswell.

He said that if i was okay with it, he would use a condom, and take it slow, because it's my second time. He always worries about me, and he told me that we dont have to have sex tonight , if im not ready, and i am. I need ideas though. Thanks.
