Question regarding transition towards sissy life

Hi Everyone, past few years, I have been interested into sissy stuffs. I sucked cock once and about a month ago I tasted my cum as well. But, I regretted immediately after pnc.
So, how can I avoid pnc? Any help would be appreciated.

Also, I am skinny and have great waist line. I would be good sissy if I maintain myself (Shave my whole body). So, Can you tell me how can I shave or what to use? Cause I haven’t shaved myself before.
