hey guys- this is sort of embarassing and frustrating. whenever i'm jacking off, i have a real hard time going straight from pumping it to cumming. i usually have to hold in my cum until i can get to a garbage can or something so i dont cum everywhere on me. basically i have some sort of mental block to cumming on me/getting messy/etc, which is really hurting me sexually cause i know my orgasms will be so much better if i could just go from jacking off --> cum. any advice? thanks.
