Orgasm

Ok so I’ve never orgasmed. Like ever. Not by my own hand, or by a partner. I’m only 18 so I haven’t been at this for a long time but honestly I get so frustrated! I feeling like I’m the middle of masturbating all I can think of is “ok, orgasm soon” and while I’m with guys . . . Well they’re 18 also and are fairly inexperienced. A guy has gone down on me once and I felt like that may have been close, but I really want to have one to know what it feels like lol.

Any tips for how to climax? Or have you had the same problem before?
