One of the things I do know about this fetish....is that you either love it....or you really really don't. And if you don't....then the rest of this post is unlikely to be of interest to you.....and honestly....you should probably press backup....
Personally, it is major turn on for me....but anyway....moving on....
For those of you who do like this form of gagging, I am interested to know your thoughts and personal preferences on the subject.....
For example....
1. From the drawer...i.e clean .....or from the hamper....i.e dirty.....??
2. Is it the thought of them being dirty? or is it essential that they are?
3. Do you have a preference for the type of Panties or the material i.e cotton, silk?
4. Is there a certain way they should be inserted?....to be direct....do your turn them inside out....you know what I mean.....
5. If you are in to Panty gags...are you always in to Panty Hoods as well or do some of you like either / or ....do the kinks have a link?
6. Lastly.....and i'll be honest...I'm still unable to fully answer this question myself.....where does this fetish originate? is it purely power or humiliation based like many other aspects of bondage? when were you first aware of it? I know it is not restricted by gender...i.e....my girlfriend likes me to do it to her and I like her doing it to me and I can honestly say that many females prior to my girlfriend have invariably liked me using it as part of our bondage roleplay......lets just say...there were many more who liked it as opposed to those who didn't.....although I didn't always ask first

Anything I havn't mentioned......please feel free to share....
Now...this is not one of those surveys where I am seeking a kick from the responses.....what I mean is it is not a one way street.....and the only way to make this a fair exchange is to share my personal thoughts on the above up front......so here goes.....
1 & 2. For me personally....it is the idea/fantasy of being gagged / or gagging my girlfriend with dirty/worn panties. The fantasy is that she has been wearing them all day or that she takes a pair from the laundry that she has worn previously, or that she wore them to the gym etc etc....you've all read the stories. However, my definition of dirty are a pair of panties damp or wet with her arousal....her cum as such.....for example, my ultimate experiences with my girlfriend have been when she has tied me up, positioned herself so I can see her and used toys to pleasure herself through her panties until she has climaxed in them, soaked them with her juices and then removed them and used them to gag me. On other occasions, and even though I was totally unaware, she has also blindfolded me, run her panties under warm water and done the same....trust me....it worked just as well. The flip side is very similar, the thought of gagging my girlfriend with panties from the laundry is one thing but my favorite method is to tie her up tightly with her panties on and pleasure her until they are soaked.....and then I use them to gag her. But that is purely our preference.
3. Preference for type colour? she has never expressed any preference...but I guess if you pushed me i'd say....cotton.....not strictly though....
4. Based on what I shared above.....yes....we both turn them inside out and fold them so the wet crotch/gusset in forced on the tongue.....again...that is just us......like I said....power/humiliation....
5. Yes, we often use another pair of panties as a hood, pulled over the head with the crotch/gusset over the nose and unlike the panties that are used as a gag, the hood is almost always a pair from the laundry. Sometime the hood goes on first, gag in mouth and cleaved or taped with stockings, scarf, tape etc but more often, the panty gag is inserted first, hood applied and then the cleave etc is secured over that. Believe it or not, I don't have a sense of smell which I think enforces what I was saying about fantasy over reality...I think its kind of funny...but there you go.
6. I've been aware of my fetish for panties probably as far back as I was aware of my fetish for bondage....although I would describe myself as a switch...i.e I like tying / gagging almost as much as being tied / gagged. I have put much thought to the origin or basis of my fetish for panty gags and although I realise it must be something to do with panties being an intimate female item of clothing...I can honestly say that I haven't really got to the bottom of things (excuse the pun).......so by all means enlighten me with your own thoughts opinions.
Finally I would just like to say that I hugely appreciate being a member of this site/group...there was a time when I never believed that I could openly discuss my fetish for bondage and certainly not my personal kink for panty gags. But it really is wonderful that I can be so open and not offend anyone.
Any feedback would be much appreciated.
