Blood does not come out without some kind of preasure

Occasionally when I masturbate blood will come out in huge proportions and even after I started using the correct tools that are made for masturbating it still happened. I used to use bubble wands and after I was told it wasn't supposed to be that way I got testing to see if I had actually hurt myself and there is nothing wrong with my vaginal cannal by what they found. I also have to use tampons for any effect and often can't keep track of my period at all (I am Intersex; swyer syndrome with activated testosterone (natural) today (2/27/2019) was the first time I felt as much pain and period indicators probably ever. I could never tell before.
