ok so I can only orgasm with clitoral stimulation. I have tried penetration for about half a year now and it hasn't worked. It feels good for about 30 seconds, but then it stops. What is going on?

For the majority of people with vaginas, vaginal entry alone isn't something that results in orgasm, just because the clitoris has so many more nerve endings than the vagina. Even for people who find that vaginal entry feels good, often some kind of clitoral stimulation at the same time is needed for orgasm to happen.
