Vaginal orgasm suddenly stops after only a few seconds /u/stuckinthepastagain3 Sex

I’ve been masturbating strictly using clitoral stimulation my whole life. I’ve never been able to have an orgasm from penetration during sex. Recently, I was having sex and felt like I actually got close to being able to have an orgasm. So I began experimenting more with trying to achieve orgasm through penetration on my own time. I’ve discovered that I can reach an orgasm, but the orgasm suddenly stops after only 3 or 4 seconds and it feels like the spot where it feels good to touch disappears. I’ve never really heard of this and I’m confused as to why it’s happening. Has anyone else experienced this or knows what’s going on?
