Is it weird that I get turned on by the smell of my dads aftershave?
That is is a little strange. What arouses you about it?
When I was a kid I could smell him while sleeping in my parents' bed. The aftershave turned me on.
You shouldn't get turned on by your dad's aftershave. That is disturbing and you need some help. That is your parent.
It's normal to be attracted to people that you live with. We lived as a family...
Even if you don't act upon it you need to stop getting these feelings when it comes to things associated with your father.
