You ladies are in the very lucky position of knowing that if you post, you are almost certainly going to get responses. But that's a two-edged sword, because if you're not careful, you will get buried in far more responses than you can reasonably handle. You may even miss out on the man of your dreams because he's buried in a ton of letters from guys you don't give a damn about. It saves everyone time and aggravation. Beyond all that, most of the advice for men counts for you, too.
Weight is a very touchy subject for both sexes, but for women it is especially bad.
Don't be afraid of this. You're preparing yourself AND whoever you meet for a letdown if you're not blunt on this subject. There are even a good number of people out there who LIKE fatness and find it very attractive. Don't be timid about it. If you're overweight, be forthright and don't weasel around the subject, unless you look forward to the prospect of being embarassed, disappointed, and hurt.
