I hate to get gender essentialist, but I'm starting to think that a lot of married men have some sort of heterosexually induced dentistry aversion.

It is so tempting to return rudeness with rudeness!

I'm of the belief that dating "potential" is almost always an exercise in frustration.

As you feel increasingly comfortable around your friends, I think it's more than fine to share the basic details of your heroin addiction with them. If they seem receptive, you can feel free to talk about it in further detail; if they seem judgmental or uncomfortable, you can move on to other topics.

Arm yourself with as many options as possible before making your next move.

Don't let a friend make you feel publicly uncomfortable indefinitely just because they're probably a lesbian.

If just one person touches you without your permission, stepping back and saying clearly, "Please don't touch me" should get them to stop.
