It is standard protocol to have 1 paragraph about yourself, and another paragraph about the ideal mate you are seeking.
If composing such paragraphs are hard [& yes, it is,] then take a look at some of the paragraphs that other people have written up, and adapt them to your needs & wishes.
In addition to these 2 paragraphs that your Dad is advocating you to compose, you also need a photograph:- A picture is worth 1000 words. There is absolutely no way around this one. I am sure your Dad will concur, and he simply forgot to mention the picture to you, or he just understood a picture to be so basic, that it never crossed his mind, that you wouldn’t automatically insert a picture.
BTW after you have composed a paragraph, they can be redacted, if you find, that based on your 2 paragraphs, you are not meeting the type of guy you would rather be meeting. & a picture can also be changed, if you after a while feel you come across better, with different garb.
I have been down this road, recently, whereas your Dad has probably not been down this road in over 2 decades, so my advice is sound & up to date.
