I experimented years ago with very large forms. I was very big (obesely overweight), so I figured it would be proportional, and I also wanted to feel the weight. I'd never had a partner, so I had great deal of curiosity about them.
Now fit and healthy, I'd really not like anything more than a decent B cup, it would mess with my sports too much!
For countless reasons, the body we'd like is an individual thing. The great thing about breastforms is that we can try different sizes, something cis-women don't get (short of surgery).
Social interactions are a very important thing in learning the female dynamic. I think you're being wise to seek these out, and hopefully find some here too. X
