Conflicts while talking

I always have the same conflict. Whenever I want to express, that a certain number of talks belong to the user, I say user.talks. No problem with that. 

But then there is such a like the talks a user participates in. Do I call these user.participated_talks? Ugly... I could switch the first one to user.my_talks or user.owned_talks. Not much better. Feels a bit crusty...

Not to mention the think-a-lots I stumble upon from time to time. Which one was what?

Any suggestions?
