Is it normal to have blood circulation cut off to the legs with only an iPhone sitting on my thigh?

So I usually have my phone while sitting on the toilet at my house and when I set it down on my thigh after about 20 seconds I start getting the tingling in my foot, a lot. IIm 155 pounds, 17 years old, live in Washington (state), eat a good variety of food but a lot of it. IIm not fat but I do have a sizable belly.

Probably your pants cutting off blood flow.

It's not your phone, it's the toilet seat itself cutting off circulation by pressing hard agains the behind of your knees when you sit down. Happens to me all of the time, completely normal

I think this is abnormal.
