A man who makes himself sound like a jerk will probably get more responses. This is based on a statistically invalid sampling, however. You're at a disadvantage. On the internet, men still have the role of pursuer. Women rarely respond to ads.
Men do most of the responding.
Women who seem attractive are overwhelmed with mail. Do not expect responses from your ad. Your ad is reference material that a woman might look up after receiving mail from you. You may get responses from your replies to women's ads. If you are shorter than they asked for, or the wrong religion, or one year too old or too young, or don't dance when she thinks that's important, don't waste your time.
