What Those Ads Get Right, and How to Write Yours
Both ads lead with age and a short phrase that sets the tone. Both say exactly what kind of arrangement they want and when they're available, which answers the first three questions any reader would ask. Both name their limits without apology, and both end with a line that invites a reply. Neither mentions anything crude, and neither needs to; a reader knows precisely what's on offer.
Write yours in the same order. Start with your age and one line that sounds like you. Say what you want in a single plain sentence. Add your availability and how far you'll travel. Include one detail that's genuinely yours, a habit, a place, a strong opinion about breakfast, because specifics are what readers respond to. Finish with your limits and something easy to answer. A few phrases kill replies, and they're worth cutting before you post: "no drama," "just ask," "not sure what I'm doing here," "I'll tell you later" and any list of what you don't want that's longer than what you do. Each one tells the reader you haven't decided yet, and the people who have decided move on to someone who has.
Then choose a photo that shows your face clearly in good light, without your house number, license plate or workplace in the frame. If you'd like to keep your face private at first, say so, and offer to share once you've talked.
