I just think that the difference of what is allowed on this forum and what's not, should be in the content itself and not on the intentions. If the content is intentionally pornographic (pictures of private parts, and erotic stories for example), or if it degrades or humiliates people (calling others sissies, or other derogatory terms) it should be deleted and the poster should be warned or kicked out. If one is simply posting about the reasons why they decided to grow boobs then it's a different story. Growing boobs CAN be a fetish (it is for me) and it may be for sexual gratification. While it probably is a step towards the correct body image of a transgender girl, it can still be classified as body modification for males staying males. I won't go about telling transgender girls that it's a fetish for them, because I know how annoying it is when someone calls me an egg just for being on this forum.
I think we should put a stop to total nudity that nothing has to do with breast growth. I am not squeamish and I've seen plenty of porn images, but there is a difference between posting a picture in a bikini bottom to show hips feminization (which is borderline acceptable when talking about "side effects" of methods to grow breasts), and posting full nudes posing like a pin-up.
The thing about porn is debatable. I know porn content creators (IRL) who are happy about what they do (both TG and GG). The industry may be degrading most times, but I don't think that the aim of this forum should be to fight a crusade against porn. Many people here have first encountered the idea of gender fluidity through porn. I, for one, started crossdressing when Internet was a thing for universities running an 8088 mainframe, but it was only through porn that I first saw someone with breasts and male parts. It did indeed condition what I want, my fetishes, but it was a hugely freeing event.
As the LGBT movement wrote on posters at the London Pride "Some girls have a dick, get over it". There are very many trans women out there who are perfectly happy with having both parts. If we accept that gender is a spectrum, then wanting a girl with extra parts is as legit as wanting a redhead, a short girl, or a blonde one. I had a fetish for asian girls and I married one. I can't see the difference with the people hoping to find a girlfriend with a dick. And yes, most probably they qill have built that preference using porn, since it's not something usually shown in biology classes in secondary school.
So, again. Let's limit the content we post to what is not directly offensive or bottom nudity. We can always find something that offends someone in everything that we write. Let's keep in mind that "It's not always about us", let's behave like adults and grow a thicker skin. We can explain to newcomers how to communicate and what to post around here. If they get warned twice then they can be kicked out. We all learned something at some point, haven't we?
