orgasm when masturbating

Okay ladies, has anyone ever been masturbating and it just feels too good? Like it's impossible for you to continue even though you want to orgasm. Most of the times, I masturbate by rubbing my clit, but just before I think I'm going to cum, I can't continue because it's too good it almost hurts. I need some advice on how to make it through! It's the same even when my boyfriend does it for me. It feels so good, but I make him stop because it's so good.
