What gets me going every time is scent. But I like the dirtier smells. Specifically, a girls butt. I dont know why but i love smelling it. Almost every time I have sex I play with her butthole for a few seconds and just smell my finger the rest of the time. When they leave i just smell it and masturbate for a good period. It drives me insane. A lot of girls seem turned off by it sometimes. They think its really dirty and weird I guess. Others that let me do it think its funny more than anything. I have a real hard time finding videos of butt smelling too. Is this a really rare fetish? Does anybody else have this kink? Any girls out there that like their butts smelled, etc.? Thanks for the replies!
