Is it normal to get horny from getting touched by males?

Every time a male touches me either accidentally or intentionally, I can't help but feel a little horny from his touch. Even with male relatives, my uncle would put his arm around my shoulder and suddenly my penis got really hard. I try to play it cool, but deep down I'm enjoying every second of it baby. I know it's sick to get turned on by your own uncle's touch, but I can't help how I feel.
