I've been tooling along with my WIP, attempting to maintain the sexual tension of the romantic subplot and soon have to make a decision about when and, possibly, if, Lillie and Johnnie get hot 'n heavy.
The timing of erotic scenes is, I think, important to sustain reader interest, particularly if one keeps in mind the possibility of a series of stories involving the same major characters.
When the heroine is not inclined to be polyamorous, one does not have the same leeway as, say, LKH.
Tantalize too long and the frustrated reader may think, "Get it on, already."
Introduce the manaconda ( thank you, Vanessa Jaye!) too soon and the reader might feel everything subsequent is epilogue.
I think the timing is important even if romance is not the only or primary plot line.
Setting skill aside -- which can make anything work -- what are your preferences for sex scene placement?
And does this preference alter based on whether the story is a single title or part of a series?
We've all had fun with the various plum purple euphemisms for male equipment presented for our reading pleasure by writers caught between the rocks of cliche and the necessary hard places.
From my spam filter, I've noticed that the purveyors of male enhancement seem to suffer from the same disfunction -- with openers such as "body part monumental," dick monolithic" -- and the one which provided an instant flashback to the upright in my grandmother's parlour -- "thumping erectile organ."
