I act like a little girl in order to de-stress.

I think you pretty much answered your own question in your post- you don't really give 2 fucks if it is or is not normal. I'm all for people engaging in whatever their sexual fantasy may be, as long as it takes place between two consenting adults and does not involve and child/animal abuse/health hazards. I think that if the rest of the world was a little less judgemental about what is or is not sexually "normal," then perhaps more people would be comfortable opening up to their partners about their own sexual fantasies- even if they are more vanilla.

I don't think you're hurting anyone- so fucking rock on, little lady.

Tbh I'm not normally one to judge about kinks, but I find this particular one to be pretty disgusting... you're pretty much aroused by father-daughter incest. Inherently unhealthy relationship imo.

I think OP is a 50 year old man

To be completely honest anything to do with BDSM kinda turns me off.

Usual-yes, fine-you aren't hurting anyone but it is not healthy. It's still your life and you can do as you wish but my advice is to find other ways to get comfortable and be stronger person, an adult individual.

well it's normal for me

Really quite common, although I dare say with the public stigmas of BDSM, Incest, and Child Abuse, not a lot of DDlg couples are "open".

As far as the BDSM part goes, it's probably at the "leastmost" end of the scale. lg's don't get trussed up like a chicken, and any form of corporal punishment is generally limited to a sound spanking of the bottom (barehanded usually). Additionally, lg's are generally less submissive than traditional "bottom" partners in BDSM - and are even expected to be a little willfull, cheeky, mischievous, etc.

The Incest component is a misnomer. "Daddy" is a term used to denote the Dominant's "Upper" position, much like "Master" would be in a more traditional BDSM relationship. A Daddy role portrays a more openly guiding and caring position, where the dynamic seeks to duplicate (in many ways) a father-figure, as opposed to an actual father.

As for the Child Abuse, again this is a misnomer based on the lg's desire to be guided and controlled by an adult. I have NEVER heard of a child of any age actually seeking to be in a legitimate DDlg relationship, and I dare say that the DD would probably not be interested in being the Daddy to a real "little girl".

From what I've seen and heard, generally lg's are mildly submissive, and somewhat emotionally immature women who don't like being "adult". Let's face it, adult sucks - you have to make decisions, be responsible, etc etc. As a lg, all you need to do is pout a little, and say "Daddy, I can't do these hard tax forms, I'm just a little girl!"

Not sure I personally agree with the bottle feeding and pacifier bit (I think I'd like my lg to be a little older), and diapering including poo would be a Hard Limit for me (had enough changing nappies with my own "real" kids), but whatever rocks your boat and gets you into "little space" is fine.

Enjoy your lifestyle, and don't forget to make your bed.

It's apparently common.

It is a state from a point in your life where you felt safe and secure, in addition to this.. while roleplaying in that "space" you have no worries, no hassles, no bills to pay.. Just carefree enjoyment of life.

So, good on you I guess. I do suggest you look for additional coping mechanisms because it is possible that you found this via a break of sorts, within your mind. If this is your only escape from that which life throws at you then you may turn your escape into an obsession and it may become very unhealthy. If you maintain it in good measure, it will likely serve you well.

Well I can't say whether it's normal or not (I think psychiatrists might have an opinion on this one), I guess everyone has their own kinks, but since you want people's opinions I think it's weird, I mean wanting someone to dominate you or take care of you in a certain way is ok but I think calling him daddy is weird, and if you didn't think so too, you would be calling him the same in public. Anyway whatever floats your boat, Enjoy!

Not normal (obviously) but I suppose it's better he does this with a role playing adult than an actual child. The only thing that I find particularly weird is calling him Daddy, it just has too many incest connotations for me.
