This is not just an issue for the LS, of course. It affects all aspects of human interaction. Healthy norms and social norms are not necessarily aligned. The "average" American woman is size 16 in dress sizes.
There is the myth that every woman in the LS is a pinup model, every man is a cross between Brad Pitt, Tom Cruise, and {your screen idol here}. It just isn't that way. If you want to see what the LS world looks like, imagine yourself at the mall, at a community meeting, in a restaurant...and look around. That's the physical piece of it.
Where LS people tend to be a bit different is that they look forward to having a bit of fun. Bear in mind that 2/3 - 3/4 of the world are introverts, and that is no different for the LS world. LS people do, however, make a conscious decision that they are going to have fun, and that begins my setting aside their self-perceived vulnerabilities and 'putting themselves out there' socially.
Among the many rituals of the LS is 'getting dressed up for the date'. Part of that is a conscious decision to make the body each of us is assigned look, feel and smell and taste great. Having date nights 'just for you' --getting dressed up for each other -- is a way to start. What you'll find is that others at the restaurant or whatever will pay attention to your spouse and that sort of gentle flirting feels great.
Ultimately, it's the conversation that really makes people interesting...or not. The body part that is actually the most important is the one that lies between the ears.
