Fetishes are pretty normal for men, actually. I think the biggest thing is that you believe it is having negative effects on other parts of your life. When it starts to become an obsession and actually interfere with the healthy parts of your life, thats when you need help.

I think the best thing to do would be to go to a sex therapist. They will have more experience with these specific things like fetishes. If you really want help for this I think those would be the most appropriate people to ask. Especially because all the things we would probably suggest you have already said no to (i.e. being abused as a child etc....)

I think in a way everyone wants to be babied sometimes. We might pout or throw a fit or do something else seen as childish but yours is considered "abnormal" simply by societies standards. It's not "normal" to pout at 33 either but its definitely more accepted. I have tattoos and piercings and get looked down on by a lot of people for that and for being a smoker. Its not that its "abnormal" to like body art, its just not typically what "professionals" do lol
