Some people will be ok with you having guy friends and exes who are friends. Those are apparently the people that you personally want to date. So thank your lucky stars that you weeded this one out early.

While you don't have to put all of yourself out there right away, I do not think that it is generally best to "hide things for the sake of a date." If you want to meet someone that you are compatible with, then that would be working at cross purposes with your goal.

I have opposite-gender friends, and am friends with my ex. Same for my significant other. No trust issues. Compatibility is a good thing.
