Mid 30's, 3 kids, married 10 years, red pill for 8 months and my marriage is excellent but I would like some advice on 1 topic.

Sex average 5 nights a week, wife initiates about 40% of the time and quality is also great as she is very enthusiastic. But it's not the quality or the quantity that is frustrating me, it's the diversity. She likes to have sex in about 7 different positions and even buys sex furniture to spice things up, but is strongly opposed to doing anything else or further experimenting. She gives BJ's and even initiates those but they are a pre-cursor to sex. What's completely off the table is anal or any anal touching, shower sex, anything aggressive like hair pulling or pounding, sex other than when the house is empty or kids are asleep, etc. Essentially she has a list of rules and she's not willing to experiment any further. Of course over the last 10 years I've attempted to incorporate some new stuff into the mix but always met with resistance. I might add she is ultra religious and sees most of that stuff as dirty or slutty.

My SMV is high and Dread Level 3, I'm often gone living my life and just having fun.

What's the advice to get your wife over these bullshit sexual rules? Half of me thinks just be happy with what you've got, the other half thinks what the shit is going on with the stupid rules and how do I keep the next 30 years exciting?
