My dad has known I am gay and was fine with it for years.We were on a family vacation and stayed at a condo.My dad walked into a connecting bathroom and ran into my boyfriend and both of them were naked.My boyfriend is really hung and my dad hasn't liked him since that day.My dad is big and was always bigger than me but is smaller than my boyfriend.He walked in on a guy fucking me once when I was 16 and even liked him but he was smaller than my dad.
