With the proviso that I'm likely to be an outlier, there's no such thing as too g-rated for me. I like all of your photos but one (you're not looking at the camera and it's a little less personal that way). The only quibble and not something I would have noticed if I hadn't been looking for something to criticize is that you look slimmer in the photo of you in business clothes. It may be a trick of the camera, it may be just a week you weren't eating carbs. Whatever. I just like seeing some consistency in things like facial hair, weight, hair color.
As far as your general question, I'm all for g-rated precisely because I've had a lot of experience (which is code for fucked enough people to populate a concert hall) and what sells me every single time is humor, a pleasant expression, and intelligence. I think you capture those qualities pretty well. So, just take Velma's advice, refresh and rotate your photos periodically, and increase your chances by finding meet and greets that include single men.
