I wonder how many of those are looked after by men. I suspect the minority
From all I've read on here over the years men maybe just don't engage in an environment like TP as well as women do, hence last years figures say it's 84% women and 16% men on here, down from an 80/20 split the year before.
You may suspect men are in the minority but it may be many just do it in private, I post quite a lot on here but I'm maybe an exception.
It isn't that the site is in any way sexist it's self selecting, those who want to engage do others chose not to, possibly women are more open to discussing things where men are not, possibly men see asking for help as a sign of weakness, who knows we're all different people.
The bit " I can find is threads about man problems such as posts about male body parts, male bodily functions and male sexual activities. Why are their no equivalent post about females." There are all over the place, the only sticking point may be that male sexual activity is the "dirty old man" syndrome where my granny flashing her knickers at ever family gathering was seen as funny (back in the 60's).
If there's an issue you want to raise start a thread, as with anything in life some will agree with you and offer help and advise and some will take a different view.
