f you're going to go for a mutual tail scene, then you'll want to try to use pronouns like "yours", "hers" and "each other's" to avoid over-repetition of "tail". Since you're going to have paragraphs going on and on about tails, try to minimize the need to reuse the word through the use of pronouns, though the occasional repetition will likely be unavoidable, especially for the mutual scenes. Remember as well that you can also toss in 'appendage' in substitution at one or two points in the paragraph when you can no longer get away with pronouns.
Using the taur list to check for usable tails probably isn't a good idea, as that includes such things as the centaurs, whose tails probably aren't suitable. Most of those in the Tailweapon category should be fine, though there is a lot of variety between them and some, like the insect ones, are quite different from the others. Also, though it's not listed as a tailweapon, the Cerberus with its tailcock setup might make for a fun special variation on this if you want to include it.
