Struggling to orgasm

Okay I’m dating this guy and we both caught feelings FAST.. like super fast. We connected really well and things are going great. I enjoy the sex A LOT. Everything about it. I just struggle to orgasm. I don’t know if I’m too much in my head about it or what. I’m never able to by penetration alone. Which is super annoying. He’ll try.. a lot. I just feel like I take too long 😭 I don’t know what to do lol
