M4A Looking for rules about edging and whether I get to cum tonight!

I am about to head out for the afternoon, but when I come home I'll follow any instructions from here about what my evening and night will look like.

I haven't cum in about a week and I've been really horning stroking to non nude pics.

A little more about me, I'm very deep in the friendzone for my best friend, she is gorgeous and I haven't seen her in 3 weeks because she's started dating someone new and has been ghosting me. I stroke to her pics all the time.

I'll let you decide, do I have to do more edges tonight? How many should I have to do? Do I get to cum or do I have to keep denying myself?

Are there any rules I have to follow about when I have to edge, how many times I have to edge to certain photos, etc?
