Clit problems?

Okay this is embarrassing to have to ask but I need to know 😂😭 when ever my bf gives me head or plays with my clit with his fingers it gets to this point where I CANT deal with the feeling anymore. It doesn’t feel bad at all it actually feels good but like for some reason it’s so hard dealing with that pleasure like I usually have to discreetly stop him but I feel like if I don’t it’ll lead to an orgasm? I’ve never had an orgasm so idk but the stimulation is so powerful. Is it normal for it to be this sensitive to the point where it feels toooo good and I actually can’t stand it happening for longer then a few seconds?
