More angry? IMO anger should be fleeting, not something to look for more of or hang on to because anger eats you up inside, chews you away piece by piece.

Lust could be serious but it could also be light and fun, depends on the moment.

If role playing makes you laugh it could be you're not comfortable with it and it's not for you or you haven't found what kind of role playing you are comfortable doing. I'm not a big fan of role playing as in pretending to be the naughty nurse or the bad school girl, etc. Those things just aren't for me, him a Dominant, me a submissive, we're not pretending, it is who we are.

Guess my "role" alternates. Sometimes I like to be dom, sometimes I like to be sub, relax, coast, and let her do the "work". Guess I haven't found the right girl yet.

Thanks, and rock on! Glad things are going well for you!

I don't see anything wrong with laughing at yourself in the bedroom. It helps keep the mood light and fun. Personally, during roleplay, I usually giggle like a schoolgirl... regardless of whether or not I'm actually a schoolgirl lol

My wife does the same. It's all part of the fun.

I find a good giggle during foreplay to be a turn-on most of the time. It gets us relaxed, and I find it very bonding to laugh together.
As for effective roleplay, it takes being able to stay in character, and not everyone can. You could always take an acting class! They're fun anyway.
