I have a problem with weight.
Weight is a very touchy subject for both sexes, but for women it is especially bad.
The simple fact is that most women believe they are overweight. 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. We live in a culture that values thinness, but there are a lot, and I mean a whole lot, of people out there who genuinely do not care about weight. There are even a good number of people out there who like fatness and find it very attractive.
