Virgin

Hi guys I need some help I’m 16 and have been with my boyfriend for awhile now. I have gave him a handjob and he’s fingered me a few times and I’ve orgasmed I’m sorta nervous because me and him are planning on having sex on my birthday which is in 3 months I’m ready but I don’t know if I will orgasm due to the fact that only clitoriol stimulation does it for me. I’m also nervous because he has had sex before and I haven’t , I’m super tight atleast that’s what my boyfriend said when he fingered me. Is there any pre sex advice to make me comfortable and less nervous? I’m a very shy person ❤️ thank you all
