I see alot dating profiles that try to grab your attention with those sleezy one lines for example a guy might have (Sexy Teddy Bear). To create an attention grabbing online dating profile I would use a warm friendly one line without any sexual overtures otherwise you might get the wrong attention. A nice profile could read for example; My Heart Is Missing Its Other Half. With a profile such as this people will take you serious, and believe you are not just one of those folks who is looking to play games online. Hope this helps.
