Struggling to orgasm 😣

Ka

I'm in my late 20's and still haven't managed to have an orgasm 😔 I haven't had many sexual partners (and tbh they were pretty bad) so I'm kinda a novice at sex, and I'm pretty vanilla 😑 But with my current bf, we have good sex - I start to get close almost every time, but never make all the way. I think I'm overthinking it and putting pressure on myself to come instead of just enjoying it. Since I've never had one I'm nervous of how I'm gonna react when it happens 😳 Does anybody else who's struggled with this have tips on how to let go and relax? any moves that make it easier?
