Im nervous

So I’m 15 and i have a few sex toys.

i have a dildo, a vibrator, a butt plug and plenty of lube. (i bought them all from amazon with my own money)

But for the past couple months, whenever i cum with my vibrator (which is the only way i can get myself to finish) it’s painful.

It feels sharp and super overwhelming. like I’m being overstimulated in a bad way. it’s so much at once, and it’s not a good feeling either.

i turn the speed down super low once i hit my climax, but it’s still very uncomfortable.

It’s only in my clit which draws out something being wrong with my pelvic floor…

I love masturbating and i know the ins and outs of my body, i don’t know what could be causing this.

Any advice?
