First time tips

I’m planning on having sex with this guy for the first time. It’ll be my first but I’m sure he already has experience. I would have definitely already had sex with him if it wasn’t for the fact that I’m a virgin. I’ve been considering having sex for a really long time now and I want to this time. The thing is I’m super nervous because I’m inexperienced. The only reason I had been so unsure about it the first two times we had initially been making out and whatnot was because I’ve never did it before.

I’m assuming I should probably give him head too? I don’t know how to really turn on a guy and stuff. Also, what are things I should do before having sex? When I shave, I get razor bumps and I’m a little insecure about that but it’ll most likely be dark so I doubt he will see. I’m not too big on the receiving end of head but if he offers, should I let him if we have no lube? I also have a septate hymen and I’m worried that it’ll get in the way, does anyone know what to do about that? Should I move the tissue to the side or what should I do? Will that also prevent it from going in?

Honestly, I’m just nervous in general so I’m just asking for tips to prepare myself before and during :) Anything would be great!
