I like a brief introductory letter that helps me to assess a gentleman’s personality. Being concise, unique, honest and forthcoming with references go a long way. I might sound a bit narcissistic, HOWEVER, (and I capitalize however) I do like it when he tells me what prompted his interest to contact me, and also what are his plans/thoughts for our rendezvous (it varies, though!).
After cross-checking his particulars, I'll then start with the verbal jousting.
Words are like an element that is used to fuel an internal fire in all of us, therefore, I like using subtle innuendos as means of weaving a cocoon of seduction as we’re emailing each other; so that when we do meet I want to just rip his damn trousers off; instantaneously.
I like it when we keep things fun, fresh, interesting and flirty until the day of our rendezvous.
