I've considered dabbling in romance. I would consider it the same as any piece of exposition or action.
"Life with the boring parts taken out."
If the sex is boring/irrelevant to the story, skip it, take it out. If the sex is central to the story, it may be erotica instead of romance. If it's somewhere in the middle, consider using metaphor along with a few telling details.
Telling details. You might only mention a few details of the encounter among the metaphors as important to the plot/characterization. A lot can be said about a man who is highly aggressive and only takes what he wants versus a man who takes his time and goes out of his way to explore and see to her needs. Neither guarantees the man is bad or good respectively, but if you have a feeling for your ideal reader, you should have an idea how they'll feel about different sorts of men.
The call about how much women want to read about can only be made through reading and writing experience really. Unless you're writing *for* a particular person as your motivation(personally highly recommended
) then it's just a judgement call. Ask the important people, agents, editors etc about how much detail they want. Is their target audience the sort that are turned off by a play by play or the type that go into a pleasant dream/trance state reading those sorts of passages. Both exist.
