Just wondering if Vaseline is an okay form of lubrication... I notice that the container says, "for external use only," but I am wondering if this includes vaginas! Thanks. You're hilarious.

I have started "cock-stuffing" in the past year or so. I use a glass thermometer and insert it into my urethra. I know that this is wildly dangerous — as the glass could break — but I thought it safer as it is manufactured very smoothly.

I know other men who use a variety of implements — pens, markers, tubes, etc., but I have only done it a few times — and it seems that the glass — while not safe as it could break — is safer as it must surely be smoother.

I use my own saliva as a lube — as I am not sure if a personal lubricant — i.e., Wet, KY jelly, or the like, is safe. Not that putting a piece of glass into your urethra is all that safe to start with.

My question — in the end — is personal lube okay to use? Is this a common fetish — I don't do it often — and it doesn't seem to affect me adversely afterwards.

Thank you for any light you can shed on this.

I was wondering what exactly a cock ring does? And has it been known to be effective at what it's supposed to do? I have seen them in several places and have been too shy to ask exactly what their purpose is.

What does one do when they are desensitized to their vibrator and need to check a consumer report before investing in a new one?

Are there toys that guys can use for masturbation and how do they work?

Recently I have discovered if I change the settings on my shower head so the water pressure is harder and faster it works wonderfully as a tool for masturbation. My question is, is there any health risks for using water for self pleasure? My main concern is getting water in my vagina...could that cause issues? Thank you so much!
