I like your new avatar - That's a sophisticated look for Lazuli/Android 18.
You put a smile on my face with that God joke!
Your foster mom let a thirteen year old you sleep together with thirteen year old boys in the same room?!? She must have been very liberal! Most boys around that age start to wonder about and explore the opposite sex and if unsupervised, well, lesbian or not you could still get pregnant. At that age, boys will start to get uncontrollable erections and try to find an "outlet" or else start to experience "Wet Dreams". After all, it is the age when puberty starts. What kind of school do you mean - College (Two year Community or four year college/university?) or High School?
I know of that classic late 1980s anime (As well as the manga from which it was derived) but I never watched it (Nor read it) because the series was too long. I know that after being cursed in a magical springs in China, Ranma changes into a girl whenever he is sprayed with cold water and back into a boy whenever she is sprayed with hot water. That plot is so well know now that even Robot Chicken made a parody of it ->

I heard that it had around 150 episodes and I knew that if I missed a few episodes that I would have a hard time trying to piece together the missing pieces. So, I passed on watching it. Besides back then, I was still watching Star Blazers, Super Dimensional Fortress Macross, Genisys Climber MOSPEADA and a few other sci-fi based animes. Recently I've been "rediscovering" via DVD, a classic 1980s anime series that never got aired in the US called
Dirty Pair and its 1990s re-boot
Dirty Pair Flash.
I'll see what I can find out about Ranma 1/2 and try to determine why you might like the character.
