Help me achieve the Big O solo!

Hey guys! So I would like to know how to make myself orgasm. When I was younger my mom walked in on me with my hand in my pants( I wasn't doing much just trying to go familiar with whatever was fun there😅) anyway she made me feel terrible for it. I was actually grounded. Ever since then I haven't touched myself. I've had plenty of partners help me achieve orgasm, but I've never done it myself.  I would just like some tips and pointers on how to do it. I've rad articles and had tried recently, but I'm just left feeling stupid and awkward. 😒 I'm very in tune with my sexuality aside from this one thing. I'd like to liberate myself and feel more in control of my body. Thanks in advance!
