Blue briefs and socks

My whole life I’ve been turned on by two things. Firstly, catching a glimpse of men’s ankles as their trousers rise up when they sit. Strong ankles with dark blue socks make me very hard. Secondly, dark blue briefs. Dunno why just does. Always been more into legs than chests. Anyone else?
I have to agree, the colour blue always gets me. Blue socks and undies are so hot!
