More likely once with each hand, once with the spouse.Even if that 3x a week is all on the same night, amiright!?
I see a lot of exaggeration on a thread populated by former science nerds who I suspect actually went through long dateless stretches during college.
Most men want sex multiple times a day. Many of their spouses want it far far less frequently. If you can compromise at 3x per week that's awesome but as you get older, busier, have kids, stresses, that usually becomes an unreachable ideal. That's part of the reason the porn industry is a two billion dollar industry.
