Too much stimulation?

So, I just became sexually active about almost 2 months ago, and I’ve orgasmed a total of 3 times. Ever since then, I no longer can. My boyfriend and I are still exploring and experimenting since we were both virgins, but any time we have sex and he touches my clit, it gets so stimulating to the point of pain sometimes. I’m really confused and kinda concerned if something is wrong with me or if this is normal. We do have sex (protected; birth control and condoms sometimes) pretty often, wether it’s regular or oral, but I never orgasm and I really wanna have that feeling again.
