Will a doctor know if you touch yourself at night when they check you up?

Answer 1

No a doctor can not tell

for both male and female a doctor can't tell if ones privates have been played with

for girls the only way a doctor can tell is by the hyme which isn't very reliable because it can break by doing normal activities

for guys there's no way to tell because the penis is always being touched and an erection has no traciable evidince

so all in all a doctor will not find out
