How do you have a mastubration alone?
set the rite mood make sure you will not be disturbed for a while get a dildo or use your fingers and go to work since your doin it urself you would know what you like and dont like
i do it in a bathroom where i know no one is around.like if people are in the family room i go to the up stairs bathroom to do it.or wait ill there asleep or not home
just make sure your are alone and set a mood!!
