COF is popular because of porn and overrated. I tried it a few times when I was much younger (not with SPs) and while it was exciting at the moment, I think I grew out of it. The result had an allure, but the feeling of CIM (or throat!) is much better. It could also be because the firehose is slowly but surely transitioning into a small trickle.
As for A2M - I've done it with 2 non-SPs. It happened in the spur of the moment and yes, there was alcohol involved both times. The sex was crazy with both these ladies and we had very few limits but it was still a surprise.
Shit, now that I am thinking of it, maybe I am how a A2M man looks like...
