One of the things that makes me shy about seducing women is the fear that women will be disturbed by knowing I like them. It's hard to tell if a woman will be happy or angry if I give them some flirtatious comment, and I really don't like the thought of making somebody I like angry. That really defeats the object, which is to share happiness with them.
I'm not entirely sure what the truth of the matter is. I've seen situations where people suffer a hidden crush on somebody, wishing they'd show some sign of reciprocated interest, afraid to show their own signs of interest without seeing some from the other side first - which is a non-starter if both people are doing the same thing. And I've seen situations where a hopeful fancier keeps hinting at the object of their affections, who then feels awkward trying to turn them down because they're being too persistent and not taking no for an answer.
Both of these situations are really failures of communication. In the former, both parties are too scared of making an unwanted advance to tell the other party that an advance would be welcome. In the latter, the pursuer doesn't know the pursued is realising they're asking them out, because the pursued is shy about rejecting them so keeps being oblique and/or the pursuer has trouble getting subtle hints, so the pursuer slowly increases the intensity of their attempts in the hope that it'll work eventually.
It'd be great if we could wear our hearts on our sleeves, and make offers without fear, and reject offers without fear. But that only works if everyone does it. If I started being all confident and open about who I fancied, then the shyer ones might feel awkward and uncomfortable, leading to them panicing and destroying the entire relationship - even if they were interested in taking it further.
But I think people should try to be a bit more open and clear, nonetheless. In the long run, that will help the shy ones to become less shy as they'll see more examples of such interactions being played out around them, giving them more confidence in their own. And in the short term, I think it'll be worth it if it's not taken too far at first; just be aware that the person you're trying to seduce might be shy, and be sure to give them an obvious way of rejecting your advance without having to feel they're being rude, so it needn't make everything awkward. Don't assume that an initial squirming away from your offer is a rejection, but also don't assume that this just means you need to try harder; watch their body language carefully - do they seem uncomfortable in any way? If so, you'd probably best change the subject. But do they look a bit excited and blushy? If so, then back off a little, but try again later, perhaps a little more gently and indirectly!
