Before I answer your question, please believe me when I say that I'm not here to try and get your attention. (I AM old enough to be your father)
That being said, as you have discovered, nothing has changed much since you were last here.
There are still plenty of jerks to go around and far fewer, quality men to answer your call. (not MM's fault) The ones that DON'T answer your profile requests are the ones that DO read and know they are not who you are looking for. Please keep that in mind (although it probably won't help much).
If it helps any (again, it probably won't) I'm having the same difficulty as yourself, only with much younger women. Apparently they don't read so well, either!
