Im in my early 20s!!!

How do you make sexual moves on your crush, I’m really ready for sexual contact with this guy, but each time I wanna go for it , I get hella nervous, I have no idea why he’s the first guy that got me like this , most guys usually try me. My crush says he don’t want to mess up things or things to change . He also is very nervous about it and he’s very experienced, he says I’m the only one he got like this around... and he don’t know how to fix it. Should I just call him over and attach him sexually or just keep waiting. We barely kiss each other except 3 times , when I wasn’t intoxicated. I know he likes me very much, but I’m so freakin horny 😾😿, I barely can look at him without getting wet. What should I do?
