If you're going to use that theme in particular, you're going to need to use some more organization in your posts to make it look more attractive. Each post just looks long and boring. Get some bolded text in there, some underlines, or something.
Secondly, format your adsense ad on the right there a bit better. Try removing the border around it, making the title of the ads pink, leave the black text (the actual content/body of the ad) in the ad as is, and try changing the link at the bottom of the ad to pink. All of this is just for testing purposes, it doesn't need to be absolutely final.
Those are just a few suggestions.
Also, I haven't run any tests but I'm not sure that the pink colored website really appeals to guys. I mean, aside from starbursts and punany, what else is there? (I mean, unless you're gay [and not you personally, but in general], pink clothing has already been played out). I don't think there are many straight guys out there with a secret fetish for pink that your website allows them to enjoy in private.
It could work, however, if you choose to author the site as a female(s). You could try promoting it as a site where girls try to teach guys what they really want to see and hear....the mistakes that guys are making...etc.
You could act as a group of girls, who happen to be friends, who decided to make a website to show 'teach' guys the right way of getting chicks. I'm making up names here, but you could have 'Jennifer', 'Amy', 'Samantha, 'Erica', and 'Jasmine' take turns (randomly) making posts for their guy readers based on their every day, social observations.
Or you could act as a bunch of completely random girls who do the same thing. The only thing that you'd need more of, in this case, is names for girls. Every day a different girl would basically just give her insight on 'why guys fail', and some advice on 'what girls really want'.
If you choose to go with any of that, try to utilize the 'Posted by..' option if possible.
Of course, if you can find girls who are willing to do this, you don't have to do this all on your own, if at all. This isn't necessarily what you HAVE to do at all, I'm just going off of what I think might work for the color scheme that you've chosen to go with. Your character needs to 'fit in' with your presentation. You can always pick a new theme and go in a completely different direction.
