Well, the question is what advice to give a woman who is unattractive, but can’t do anything about it. I’m not sure I agree with the premise (most people can do something to make themselves more attractive), but it’s your (Velocity’s) thread, so I’ll go with it.
The first question I’d ask is: What do you want a man for?
There could be any number of answers, so I’ll pick one, and go with it: “I want a man to love and cherish me, and to be a good father to our children.”
In that case, I’d probably advise her to “act more like a man”: locate one or more prospects and actively pursue them. Some possible prospects could include “geeks”: younger men who have likely had little success with women, have low self-esteem (at least when it comes to women) and are not assertive. (Don’t wait for them to ask you out, because they won’t. Ask them.) Genuinely, truly religious men: they’re likely to have a different value system, compared to other men. They’re more interested in finding a good wife and mother, and relatively less obsessed with looks.
As far as how to approach them: with geeks, one good approach would be to show interest in what interests them. Ask questions, and listen. (If it bores the fuck out of you, you should probably move on.) If there’s a way for you to participate in his interests, participate. When the time comes, ask him out. Or kiss him. (If you want. If you don’t want, he’s not the right guy. Move on.)
If he’s a religious guy, you’ll have to be the same or similar religion. You’ll have to go to the same church. Do church things with him (whatever they are). If he’s still the guy you want, after spending time with him, ask him out. Do not, however, initiate physical intimacy. Be willing to be vulnerable. Be willing to use his shoulder, and if he lends it, show appreciation. Talk about your problems, and if he listens, thank him for listening. Tell him you feel better just for having someone to talk to. If fixes your problems, or tries to fix them, thank him for that. If or when you want him to kiss you, say “I would really like it if you kissed me right now.”
Anyway, the point is, if you’re a woman, and you’re not attractive, you can’t just wait around for the right guy to show up. You have to figure out what you want, and actively pursue it.
