What happened????

I am experimenting with masturbation techniques. Sorry for the TMI but today I was in the bathtub taking a bath while the shower head was on. I played around with my fingers but nothing was pleasurable. So I took it to the next step. I used the showerhead on the pulsing water stream setting on my clit while a shaving razor blade handle was in me. It felt amazing but the second I did it I felt like I was gonna puke and down there went numb and my legs went limp. I don't think it was a orgasm cause it didn't feel as great as other people described it as. But right after everything was really tight and maybe swollen and I had to stop experimenting. Anyways Idk what happened. Any possible explanations?
