I agree with the Hank Moody recommendation. Guy drips of sexuality, and while he may not be the most proactive in pursuing women, it would kind of ruin the show if he was, seeing as he plays the sexy and magnetic writer.
A recommendation that personally has helped me a lot with my game - especially in learning how to best utilize a warm tone - is Ryan Reynolds. Now I'm not only saying this because of how he was rated Hottest Dad of The Year whenever that was. I persuaded a very sweet and surprisingly freaky Asian girl on tinder when I was drunk after an unsuccessful night at a bar by calling her up and semi-modeling Reynold's voice. May have been coincidence, but women respond well to a playful and warm tone in my experience, probably because I'm very tall and decently filled out and I've been told I can be intimidating otherwise.
Reynold's tone of voice is very inviting and friendly, but he still has that masculine purr, and he is extremely playful.
I'm thinking of his roles in Van Wilder and in Deadpool specifically, though any of his interviews are also a good model if you're more of a high energy guy. If I remember correctly he switches between highly playful, silly, and energetic to more suave and smooth in both the movies I mentioned, leaning towards the high energy side always (I will admit it's been a while since I've been both movies).
He is also just very charismatic and his high energy is infectious.
Girls swoon for a man who can successfully integrate seemingly disparate qualities into a socially acceptable personality.
Here's a couple more I like:
- Benedict Cumberbatch in Sherlock Holmes embodies many of the byronic qualities of an attractive man, and you'll see his self-proclaimed sociopathic character serve him to seduce women from time to time in order to get information or favors that he wants. May not be the greatest example because, y'know, he's a sociopath (or is he? watch the show if you haven't already

)
- Ragnar Lothbrok in Vikings. Piercing eye contact, strong and graceful yet casual body language.
- Vicky, Christina, Barcelona. Actually saw this in an article on this site a ways back so you may have seen it already, and Juan (I think that was his name) effectively cold approaches and seduces two beautiful women (not to mention Scarlett Johansson stars in the film, ouuffff)
- Robert Downey Jr in nearly anything. Uses very self-aggrandizing speech but does it in a socially adroit way. This personality trait seeps into a lot of his characters.
- Will Smith in Hitch of course, that's obvious though considering he's a dating coach in the film and I wouldn't doubt most people on the boards have seen this movie. I found it pretty funny as well, but a cheesy ending. Good movie to watch with your girl.
- If you can bear it, Hemlock Grove. Two of the characters - Peter and Roman - embody classic archetypes that women consistently read about in erotica and fantasy: the werewolf and vampire. So yea, you're probably groaning, but it's basically a more badass twilight. Arguably one of the best werewolf transformation scenes on T.V, and a more interesting than usual take on vampires from 'Scandinavian?' (not sure) folklore. I say if you can bear it because it's got a very different style than most television these days, and I only really watched it because I was binging it for a weekend with a girlfriend, and the characters had her really turned on. Or it might have been me, but likely both. If anything check out the transformation scene because why not. While I can't stand the entitled and snobby traits of Roman he still has many qualities that women adore.
- Jason Momoa in general. Good in Frontier and Game of Thrones. Only a little bit of actual seduction, but his body language and actions are very powerful.
- Luke Cage. Very smooth, very suave, very strong (both literally and in fundamentals). If you dig Marvel you can get two birds stoned at once with this one.
