Yes, as a man who loves pussy, I do get aroused watching well-hung men masturbate to pictures of naked women, or lesbian porn. Or if a man is jacking off and bragging about his big dick, that also gets me hard. It makes me want to compete with him for other women.
The older I get, the more I enjoy males in my fantasies. It doesn't make me like pussy any less -- it's just getting the most out of my sexuality. Men have to be well-hung, though, to get me super aroused. I might think a man has a hot little ass/body at times, but I don't get super hard for other men unless I feel them as competition from their big manhoods.
