So there are a lot of good questions about romancing in these games, and the Romance Guide on the Wiki is awesome. A lot of it assumes that things stay pretty monogamous though, even if it is a serial sort of monogamy.
But what if you wanted to be a completely Playboy Shep? That is, having as many sexual encounters as possible with as many people as possible?
What exact steps would one have to take to accomplish this?
This question is different from the first linked question, in that although it was asking if it was possible to do so, and the answer broke down all of the romance options, it didn't deal with the specific strategy to go through to do so. The answer in that other question mostly just broke down all the info from the Romance Guide.
Since I'm a straight male, I'm more interested in a straight male shep breakdown, but providing other breakdowns (straight/bi/gay male/female, although I suppose bi for either gender would be the most player status) would definitely improve the answer.

By my reckoning, for straight male shep you have these options:
It seems to me that in order to have the maximum number of encounters, you have to carefully juggle the more "romantic" options while throwing in the more "casual" options whenever possible. Here's how I think it could work out.
ME1
ME2
ME3
It looks like the only person you can have multiple unique encounters with under this strategy is Kelly, since she is so casual and in two games. The others you'll have to settle for the once.
