My parents are renovating the house so I have come to stay at my aunts for a few weeks. She walks around in the morning and late at night wearing no pants, only a tshirt over her underwear. Now I know its her house and she can dress however she wants, but I've started to...enjoy looking at her legs, like in a sexual way, and its become really bad. More than once I actually got an erection while sitting at breakfast, just by looking at her legs. Would it be OK if I asked to stop dressing that way? Like do I have a right to, since its her house? I'm scared I might end up doing something I'll regret, and I also feel dirty that I am getting infatuated with my aunt.
