Soooo...

Ok so I discovered masturbation pretty young, and at the time I was still pretty innocent like I didn’t even know what it was yet, I had been watching a horror movie so my heart rate was up and I had my hands in my lap and was pushing down cause I was scared and I didn’t mean to but it just kind of happened and I had an orgasm and I was scared cause I didn’t know what it was but it felt good, now I’m obviously much much older and am healthy sexually active, anyway the point of this whole story aside from completely embarrassing myself is to say I can only masturbate lying on my stomach otherwise nothing happens, anyone have any tips to do it lying on you back? Cause it gets difficult on my stomach because my hair gets in my face and stuff, sorry I’m kind of annoying and it’s an odd question but just curious
