LPSG stands for Large Penis Support Group and basically, this is a place where you can go to talk to people that have a big dick. You're welcome to visit and look at the posts if you don't have a massive dong, but this is actually a site designed to be used by those that are packing a lot of heat.
It might sound silly, but having a big dick can be problematic. I'm pretty well endowed and boy does it suck to have your cock touch the toilet seat when you sit down. Anyway, less humble brag, more discussion of LPSG.
The forum has a number of posts and threads under different headings. To be honest, I'm not actually a fan of the design of the forums themselves, but they get better once you go into the sub-categories. There are quite a few areas to take a look at including relationship advice, sex tips, discussions on health and other relevant topics. For some gay bros, it's a place to see big dicks. For others, it's an environment to discuss with others the issues that face well-endowed gentlemen.
