I dont see why you cant - altho im not so sure you need to mention it really.....I was in a relationship with someone who had a criminal record, had been arrested loads of times - fair enough it wasnt anything terrible (in my eyes) - it was animal rights protests and i admired the guy for doing it, but he just dropped it into conversation one day and it wasnt a big issue to either of us. Why not just get to know someone first and let them get to know you before divulging this information, then hopefully you will have shown you are an acceptable member of the human race - if it the right person, they wont judge you anyway.....
