I've noticed a proliferation of 'girls only' groups - is there a reason for this?

So my social life has gone rather unfortunate of late, therefore I've made some rather vain attempts to 'get out there'.

On my hunt for new activities, I've noticed something quite curious.

There seems to be a lot of girl only social activities. Girl only yoga, girl only running, girl only book clubs, girl only hiking events. To the effect that I've been struggling to find some events that I'm interested in and would be welcome to by virtue of owning a rather prominent phallus.

I'm just wondering do you believe there is a deeper reason for this?

ie are men being left behind in terms of their development?

Or seen as creepy?

I've also been spotting a lot more lesbian relationships of late.

I'm just wondering is there a theme? Are men becoming redundant or being seen as some how morally debase relative to women?

Women, do you still value men?

Men, have you spotted anything similar?

Please try and give thoughtful answers rather than some kind of bitter gender war.
