Body questions

how can I stop or prevent getting the bumps in my ass that come two or three days after shaving it? I don't trust myself to use nair and there is no area to go here to do waxing

after giving head how can I get my mouth back to feeling normal? I'm autistic and am very aware of my body parts and it is very irritating when one part doesn't feel right

is it normal to leak so much after not masturbating for like a week or so? I used to masturbate every single day sometimes like 3 to 4 times a day, I have been preventing myself from masturbating but I have noticed that my underware is getting very stained now, is there a way to prevent leaking? And please don't say sounding
