I've never had an orgasm🙄

Not to say I'm very experienced but my boyfriend and I have had sex a lot in the past two months since we first started and I've never had an orgasm. Since I wasn't sexually active before him I don't know how I'm supposed to feel when I'm climaxing but I do often feel as if I should have an orgasm soon yet it never comes. The sex is amazing so I'm confused on why I haven't had an orgasm. Someone help lol !!!
