This is a guide to help you navigate that anon...

You can tell cause when you accidentally squeeze the guys ass it usually is more toned and when you work up a good understanding of female periods their asses should be much fatter if the ass you squeeze is still not fat than be careful that likely is a man.

If it is a man here is a process.

Step 1. The ass is a guys (most likely gay)

Step 2. He turns around and smiles

Step 3. You need to say either " I was aiming for her (insert girl name here), "thought you were a girl" or the last one "fuck off fag I squeezed your ass cause your a disgusting fag that will burn in hell"

While here is a process if target achievement was successful and it was a girl

Step 1. Squeeze and laugh or smile and keep walking, or say "hey baby maybe you'd like to get a drink the safternoon or you could specify a date' and the last option could be "hey baby I thought you could be a man"

Those are your 2 variables and 3 responses you could have for each variable. Your welcome.

Thank me later...
