Orgasms too intense?

I have never struggled to reach orgasm. At least, not when I’m masturbating. Intimacy with another person is a separate issue, but when I’m using toys like vibrators or dildos and build myself to orgasm I can’t ride the entire orgasm through. For example, I have a rabbit. There is the insertable dildo and the added little nub that vibrates and stimulates the clitoris. This toy in particular can get me there very quickly but once the orgasm builds and I fall over the edge the orgasm is so intense I chicken out and rip the damn thing out of me before the orgasm has reached its peak. I don’t know if I’m just easily overstimulated, if I’m a scaredy cat, or what. In some capacity I am easily overstimulated. With a partner in the past, if he was holding a vibrator to my clit with more pressure than I usually use on myself then the pleasurable sensation would overwhelm me. I know overstimulation is a goal for some folks, but why do I seem to get to that point so easily? I’d say 90% of my orgasms end like this.
