Me or men?

So I didn’t lose my virginity till I was 18 almost nineteen. I was always way to nervous to. Actually lost a guy I was madly in love with because of it. I have always been able to make myself orgasm various different ways but always found it hard orgasming with penetration. Its been a little over a year since I lost my virginity. I left the dude like two months later and have now had sex with two more men. My card holder was inexperienced, the second guy was so so, but the third guy knew what he was doing for the most part. I still have yet to have a guy make me come from sex. And my first was the only guy to make me come in general from oral or rubbing. I don’t know if it’s nerves or what. This last guy was very well endowed so I don’t know if it was from pain, but even with the other two not being big I couldn’t come, didn’t even really feel that amazing. It actually felt better with the guy with the bigger dick... am I the only one with this issue!
