I know I personally wouldn't (even before I got my own), but there's always that fear. I want to believe that if you're vibing with someone enough to get intimate, they wouldn't make a big deal out of it. Something just to prevent your partner from putting a lot of weight on it, or tugging at the area. From what I've read online, the most common thing people do is use a covering/belt of some sort and very briefly bring it up in passing. The problem I have with that is how to approach the ostomy subject, if at all.
They say it's a game of numbers plus trial and error. Friends and family all suggest that I take the plunge and just sign up a for a ton of online dating websites.
I'm in the same boat as well, although I'm a man.
