My answer to What to do if the husband wants oral sex but the wife thinks it's haraam? made me think about how Muslim spouses can have an adventurous sex life without resorting to I'm-uncertain-if-this-is-halal acts.
Question: How can adventurous Muslim spouses spice up their sex life?
I often see claims like the following online:
Sexual exploration is an open field- I mean a huge open field... -- Spice up your sex life- it's all halal!
followed by a mix of obvious and/or yawn-worthy suggestions. There's claims around that Muslim spouses are able to be wild in the bedroom, yet many things seem forbidden: masturbation, anal sex, pornography, open relationships, etc.
Some off-the-top-of-my-head ideas would be: rubbing ice on each others bodies, feeding each other, wearing sexualized clothes and costumes, role playing ("I am a mighty warlord, and we have just taken your village...").
I'm seeking something more comprehensive and general than "a bunch of random ideas I thought of". And, ideally, some method for determining the haram/halal status on the fly ("...hold on honey, I'm just Googling fatawa..." is not sexy).
