I’m not to sure what it’s like, but I guess it’s simple and cheap. U can get off ebay and amazon I think.
If you have a guy feeling and he is acting differently then there is something not right. It doesn’t have to be gurning but if his mouth is different or facial expressions then it is something. Gurning happens alot with extasy. Don’t know how to spell that lol.
It depend when he is using effects his eating and sleeping. Do you think he is using in the house? Some signs.. Going toilet alot using.. Sniffing, runny nose. Staying up late on his own.
It also causes alot of porn use and cheating. Sorry to tell u this but I’m being honest.
