Before you go and call me gay for sticking my finger up my ass while masturbating let me just tell you that it's NOT gay. If you stick your own finger into your prolapsed anus to get more pleasure while mashing your meat then it's completely fine. It's not another man's finger so your heterosexuality is safe. Infact, I recommend all men should try and stick something up their anus at least once in their lifetime. Speaking from my own experience it was an enlightening moment and really helped me understand my sexual desires and preferences. Honestly, if you don't shove something up your ass before the age of 10 like all the real men then you're probably a closet gay.
