The worst thing you can do is pigeonhole yourself. Once you start identifying things you won't do because you can't imagine yourself "getting into that", you are cutting off so much potential in life.
Nobody says you have to dedicate your life to something just to see what it's like (except for street gangs). Try things out. You may like them; you may not. Either way, you're not obligated to do it all the time, or ever again. Hell, you can walk into a situation knowing that you're going to do it once and that'll be it. It's totally ok to do it for the experience of having done it.
So as yourself what you've always said you'd never do. Unless it's murder or rape, why are you not doing it? If there's no good reason, then do it once.
