after a long time I gave it a try and told my girlfriend about my fetish of getting wet and messy and hey she is ok with it . We had some sessions with food where she liked to splosh me (she don't have a feeling of getting messy). Recently we had a session where I introduced her to slime (wallpaper paste) and suddenly we were both playing with the stuff.
So now my problem is or her that she says that she would like to have sex with slime but she is afraid that the chemical ingredients would harm her special place. So I never had any issues with my genital area, but to have it inside of you could be a problem? I am no chemist but when I read the ingredients of wallpaper paste I think about my and her health. So what will Carboxymethyl Cellulose or starch ether will mean for your health, especially for your special place?
I experimented with guar gum only and I had very nice results, maybe this would be an alternative, but what do you think? I really would like to know the statements of the girls who already had experience with it. Because I already watched those movies where they stimulated their intimate area with a vibrator or had sex in slime.
Definitely don't take my word on it without investigating further, because I am by far no expert on this, but this question has came up before. If I recall the consensus was that it was generally safe, IF you are using one of the kinds that don't have any added antimicrobial agents (which can pose a danger).
You should be able to look up all of the ingredients to see what they are, and any chemicals should have data sheets available that list any dangers they may pose. I believe most of those sheets will list if the chemical is any sort of an irritant as well besides any more serious risks.
However, if either one of you is concerned, it is probably best to find something that you know to be safe that would make a decent substitute.
I'd recommend J-lube, it's sold in sex shops as a powdered lubricant & is safe for the sensitive areas. A 280gm or 10 oz bottle goes for about $50 here, you simply mix it with water at about a 15:1 ratio, though you should experiment to find your ideal consistency. The best part is you can mix it with nice warm water to keep things comfortable for you & your partner. A single bottle should be good for a few sessions, depending on thickness & quantity. I found about 6-8 liters was enough to get both me & my girl thoroughly coated.
I'd probably skip true 'wall paper paste' - who knows what additives are in it.
Guess you could make your own with flour and water, but that sort of sounds like a yeast infection waiting to happen - and not terribly slippery / fun.
I'd second the J-lube. Had sex in it multiple times with my girl and no issues. It's actually used as a gynecological lube. If you buy at a sex shop the price does seem to be pretty high, but if you can scout around and find a veterinary service you can usually find it much cheaper.
Mix it fresh for each use and discard any unused portion (or use it very quick afterward)
My wife and I have used Xanthan Gum and methyl Cellulose with no issues reported at all. Its probably best to avoid any gun powder that has been coloured in any way also. As natural as possible is always the best way to go for her safety!
Love you, too
