I just feel like I shouldn't :/
And do you know why you feel that way? Because you've been socialized throughout your entire life to feel that way. Nowhere is it written down, nor is it a rule or law, that males are not supposed to enjoy something targeted towards females.
If anything, you should feel good that you're enjoying it, not only because it's awesome, but because you're challenging the norms of society, which is something that isn't done nearly enough these days.
