I have no discrimination for race or age on my profile simply because each person is an individual. I live in between Leeds and Bradford which of course has a large Asian community. Of the ones I have seen I have never had a bad experience with them I have had the odd "wanna be a gangster " type and haggler but they don't really make it to the door just as they wouldn't if they were white. So I see no need to exclude a particular community. Maybe it helps that I am the older end of the scale and the younger ones get more hassle.
As for the age thing I do feel a little uneasy seeing younger guys mainly because I have a teenage son and the mum side of me wouldn't like to think of him punting two faced I know given my job but at least I'm honest and I do give this reason when people tell me they are young or ask if I have a problem with it.
I have personally had more issues, rows and time wasting from what a lot of girls advertise they would really want to see the older, more mature, middle class gent than any other people. I find some of them can be obnoxious, the most likely to ask/ try for stuff you don't do, or try to push boundaries generally. They are also the ones in my experience who are most likely to ask for BB as they seem to think because they talk posh when they tell us "I'm clean honestly" that we will somehow think oh yeah you speak properly so you must be.
