Can 'you tell?" from what i read on your page, this is the infor i am gather...and i want some one to answer it 'TRUTHFULY..' ( I WOULD RATHER KNOW THE TRUTH AND BE HURT BY THE TRUTH...AND LIE TO..AND DO SOMETHING AND THEN 'FIND' OUT 'THAT WAY...THAT IS NOT THE WAY I WANT TO FIND OUT'
Here is what I gather from your web site:
So from all of this I have the following thought
a) Male--- if he LIE you can't prove the sex
b) Female---- they can tell <something been In the 'private parts'> but they can't say [exactly 'what' ...and she can lie and say TAMPONS......]
c) a dr can tell if the male 'got wet' if he dont wash good , they will SEE 'proof' DURING THE check....if a male wash GOOD then it will be no proof
'back.....' if "residue" is there for a few hours, yes--but a GOOD WASH, or 'over' time...and a good wash, CANT BE PROVEN EITHER Anus----a few hrs and cum yes....a day lstter and a good WASH NEVER
Oral.... bruse in mouth for a while....after a time. NEVER WILL KNOW
