Good for you! I applaud your willingness to step outside the box and take some risks. It's completely normal to feel awkward and uncomfortable when doing something new, but I'm positive that not only won't your husband laugh at you, he'll more than appreciate your effort - men are typically stimulated visually, with a common fantasy being a striptease.
Many gyms now offer fun classes like stripteasing, so check with your local fitness center. If there aren't any classes in your area, you can find a number of how-to DVDs at Fitnessfly.com; Carmen Electra's line of striptease DVDs is available at Aerobicstriptease.com. Don't worry about your performance. Trust me, your husband's not going to be looking for perfection or critiquing you - he'll only care that you're enthusiastic and making the effort to put some sizzle into your relationship. And who knows, you might just discover hidden talents you didn't know you had!
