How do I orgasm?

Hello lovely ladies of <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, I've been with my boyfriend for about 10 months and we've been having regular sex from about the second month. He was my first and he's more experienced. I'm enjoying penetration, however have no idea where my clitt is nor how sex is supposed to feel. I have never orgasmed and as someone who doesn't masturbate I don't know my body very well. Even though I'm into it, sometimes I just go dry during intercourse.... Why? And do any of you have any advice for making my experience better? My boyfriend is the absolute nicest ever but idk if I might get nervous or so still? Sometimes I get this overwhelming feeling but get too scared of it and tell him to slow down/stop, is this when we should keep going? Lol thankful for any advice and help 😊
