First and foremost, you are not less of a man because you have a foot fetish. It's not that uncommon for people to have fetishes for certain body parts. I'm a butt man Second, it's normal to have these feelings. A "vanilla" sex drive is no more normal than having a sex drive that is sparked by something like bisexual curiosity or some bdsm or having a thing for broad shoulders.

Since you've never been intimate with a woman, I think you're just causing yourself extra worry that you won't be able to perform per your own expectations. It's a whole different world beyond thinking about the female form and experiencing it. So I think you've got nothing to worry about there. Don't create a problem where one doesn't exist yet.

Masturbation is normal as well. Do be aware that your hand is tighter than a woman can be though so if sensitivity is an issue when you have sex with a woman it can be helpful to use different methods for masturbation. But right now I don't see any issues at all.

Okay, so now that I've said how pretty much everything about you is normal and not bad in any way ... I would suggest talking with a counselor. I'm worried you're setting up some negative thinking patterns that can affect you in the future. A counselor can help you work through the negative feelings I think you're projecting on yourself and help you become comfortable in your own sexuality. So when it's time for you to be intimate with a partner, you can both enjoy each other to the fullest.
