Is LPSG just for men?
I think it really depends on how you interpret the "for".
The Large Penis Support Group is a support group for the large penis and those who have one. By that definition it can be interpreted as being strictly for men as they are the ones with the penis. It can also be interpreted as a support group for those having dealings with a large penis, both male and female partners of an owner of such.
Hmm, so even the suport itself can be "for" both genders. Interesting.
As to giving the support, that's for everybody to provide, male and female.
I guess really who it's for is interpreted by the person reading it. Ironically, for those who refuse to interpret it as being for more that just their own small niche purpose, the site isn't really for them after all. So sad.
