Oddly, the two areas aren't related...
I was talking with another one of the ladies last night and we started on the topic of sexual joking. I ran across this post on a jiu jitsu forum and it summed it up beautifully. (The poster pops around here sometimes. If you read this, you hit the nail on the head.)
It's a violation of boundaries, a breach of trust. We can press ourselves up against sweaty strangers on the mat. We can let them do things that if they take it a little too far, can result in not being able to walk right for the rest of our lives- or even LOSE our lives via a crushed trachea or something. The only way we can do things like this is if there is a mutual respect of the boundaries; a negotiation of "Safe Space". The violation of a gym's Safe Space is a worse crime than a boob grab. People who do that &$%# need to be booted right out of the school.
Respect. It's the currency of BJJ. Violation of safety boundaries and violation of respect aren't really that different, and I'd be willing to bet that one feeds off the other.
Also, while writing this, I realized my big problem with full guard. I have too many options. I get stuck in analysis paralysis and wait to be attacked (not always a bad option, but it's not working for me right now). So, I'm going to pick just two sweeps, two submissions and maybe transitioning to spider/open guard to focus on. I have a feeling that if I don't, the loop's gonna go all infinite.
