Mmm yes it would be lovely to have a few grownup sensitive chaps around . They do exist. But I guess it is a bit like a man deciding to join the WI. Not easy to blend in without being overly demanding of attention in some gauche way - talking too much, making risque remarks, flirting, being provocative by making sexist remarks etc. I do find the same applies in real life to men in our age group. Lots of them are awkward around women to say the least. Possibly because they worked in male dominated work places.
And because they are a rarity we - the majority, do not always react to them as if they were just another person. Ranging from - ooh a man, must look after the poor dear and make a special fuss of him, through to, oh god another man, bound to be a creep, will ignore or avoid him if possible. I confess that I veer towards the second of these personally.
