If you discuss these with strangers, I see a lot of replies possible. If you discuss money, they will think you're trying to scam them. If you look legit, people will listen. I bought an investment linked insurance inside a bank from a stranger. I wasn't there looking for one, but I liked the pitch. I also sold an investment linked insurance to a stranger. Like I said, it is looking for the right audience.
If you want to talk about sex with strangers, that is just crazy. One because that is just too much info [TMI]. Would you talk about your diarrhea to strangers? Another reason is, why would strangers care about your intimacy problems or ideals. They don't know you, they have better things to do. If you go to an art community and want to be part of that community, they will welcome you with open arms. If you go to a gym and ask the stranger veterans about your fitness goals and ideal body, a lot of them will be happy to help. Like I said, it is about knowing the audience.
