Would anyone be interested
Pretty vague.
Not judging, but are you looking for two other guys? An SP and another guy? Two SP's? An SP and your significant other?
There are many SP's who offer multiway action (MFM or MFF). I'm sure if you contact one of them, they could find a third that they would be comfortable with. Expect to pay for that third, though.
As the post remains up, you may see users or SP's "like" the post, I'd suggest they are good places to start the search.
