Need HELP!

I’m having some struggles with reaching an orgasm ...I feel like I just can’t reach the point of having an orgasm. I’ve had a sexual partner I was super comfortable with and nothing, it felt good. I just never reached that point. I’ve tried taking it into my own hands a few times but I have no idea what I’m doing. Thought of getting a vibrator but I just don’t know! Any recommendations?? Hellppp
