Self orgasm intrigue

Samantha • Ohana means family and family means no one gets left behind or forgotten.
Okay so I've read on here that a powerful shower can reach you to orgasm? I am not one at all for even playing with myself with anyone but I am quite intrigued in this because when my boyfriend tries while foreplay it feels nice but I just can't handle how sensitive it feels, it's more annoying that I don't know how close I am to an orgasm so I know how long it lasts. I really really want to know what having an orgasm feels like cause I see my boyfriend going through it and it disheartens me that I can't do the same so I feel down straight after sex. So does using a powerful shower work? If it does: 
How warm do people have it? 
How long before you reach that orgasm? 
And my last question is this even normal to do? Haha 
I tired it for like a second and it didn't feel normal and felt really strange and like I'd burnt Down there (don't worry I didn't burn)
