After reading both Sinn's and Mystery's writings on seduction, I came to the conclusion based upon my own experiences it's basically a non-debate. Their approaches are not mutually exclusive.

Sinn's approach is about creating a sexual frame very soon, stating your own sexual identity in a casual style and creating seduction right away. Seduction starts at the first moment

Mystery's most famous approach - attraction/comfort/seduction stages - is all about clearing obstacles to engage sex talk and kino. So according to Sinn's perspective on Mystery, there is no explicit seduction until the third phase.

Are we talking about two different paradigms? Not at all. They are both helpful and will both lead to success. Mystery is spot on how you can eliminate a girl's resistance and give you control over a situation in a built-up way. Sinn is mainly worried that this approach is still too close to the "nice guy" syndrome, which leads nowhere.

I think it's all about having some socio-psychological skills to find out what kind of girl you are talking to. You can pretty much create attraction in a generic way. Just be somewhat original, funny and do it in a confident way. Dominate your social surrounding. Use Mystery's tricks to overcome obstacles: being accepted in a group, etc. Comforting is also very important, because I believe you need to build up an emotional link, something you can refer to when you want to have something more than a one night stand. In these both stages, you are transmitting your unique personality. But when you are teasing the girl in both stages, just use enough sexual content in a casual way to also transmit the message you are a sexual person. But also do this in stages: just find out which limits you can reach without presenting yourself as a sex maniac. The result is a multilayered framing: sexual, something emotional, something casual, etc. And the result will be the same in the seduction stage: you already made clear you are also a sexual person, but now it's time to go from flirting to sex.

Just my 2 cents. Any comments?
