I’m getting these urges of sexual nature towards my boyfriends dad. When my boyfriends hand is On my lap under the dinner table, his dad and I are playing footsies the whole time. I’ve been with my boyfriend for two years and I’ve started to get sexually fustrated because of my attraction to his dad and I get so many temptations. I picture his dad during sex, during summer when we go for family swims I just stare at him the whole time having erotic sexual fantasies.

The father is married but not happily and I often catch him staring at me and sometimes touching me

Is this wrong? Do I give in to my fantasies?
