Since you`ve got a budget limitation at present, I would work on the copywriting and communication strategy. It`s a bit unclear, or it lacks a certain sparkle. Your photo choice is certainly interesting. This is where I might normally suggest using a less - I don`t even know what word - well I don`t even know what to say about that picture. Probably not the best for a general audience. It`s racy. In my opinion you should either use a more tame picture or a more racy picture. But the middle ground is sort of boring.
But at any rate, simplify the front page and work on copywriting that really differentiates your product. Patent or not, underwear is underwear, and there is plenty to be had at Target for a lot less. Nothing wrong with charging a premium but you definitely need to justify the premium. The whole angle of support -vs- no support is sort of tired ... and a bit of a cliche. Surely you can think of something a little more interesting?
Also. Maybe it`s just me but I missed the "fun" aspect. Joe Boxer is fun. Fun is sort of a good angle I suppose, so perhaps ramp up the fun. What about a heading that said:
"Are You Big Enough?" Maybe you could even offer three sizes:
That might be fun/funny and just ego-damaging enough to drive spite purchases. So... you need to pick something conceptual ... like is it going to be endowment-based or whatever ... and really focus on that point. It`s a bit vague or all over the place at present.
Uncommon product for StartupNation but nice to have the variety.
[Here`s an article I wrote on copywriting.]
with a name like knuttsak, you HAVE to be goofy!
The site seems to take itself a bit too seriously...the whole time I was on it I felt like I was waiting for the big punchline!
CookieMonster is right on target with his hilarious "sizes" suggestion, that kind of branding is just what you would expect at knuttsak!
I want to see more "knuttsaks from around the world". Put `em on your from page! Is that guy really standing on a frozen lake? Isn`t he afraid of *gasp* shrinkage? Brave man!
Hi,
I like how you have the waistband as your banner.
Really eye catching along with the buff model. 
I liked to suggest you adding a opt-in form on the
front page, to capture names and emails of your
visitors.
Also, on each of your pages include a "Need Help
Shopping? Call 111-111-1111 Hrs 8 -9" This will
provide the visitor a sense of comfort when it comes
to knowing you are there.
As for the color scheme, I`d like to see it tie in with
the colors of your displayed briefs. Add some color
to your headers like "Support Your Boys!!!"
I suggest adding a form where visitors (women) can
sign up to be notified of the release of these briefs on
the Coming Attractions page.
One more thing, we read left to right, I`d suggest moving
the KnuttSak logo in the right corner to the left corner, just
in case your site is too wide for some.
I hope you`ve found some value in what I`ve shared.
Continue to make this an awesome day!
Won`t Be Denied!

It is all about your target market. Does your target market look like (or want to look like) the photo? If not, then a change would be appropriate. It is marketing, so if a photo like that gets the ladies to buy for their man - it works.
The page transitions (fade in/out) should be eliminated. Also you should have more descriptive titles for each page ratehr than "Home" for your home page, etc. Remember, the title is important in search results.
Home page - having the text "centered" is not the best. Use left or justified margins. Also, try to limit the multiple text colors.
You should add an alt image tag to the photos.
"Ashley`s" testimonial on the home page is shown under the "real men real boys..." paragraph. So, I would assume the testimonial is related to the Men`s product.... "Ashley" sounds like a woman`s name.

... I love the concept and most of the copy. I like the way your copy reads like a real guy would speak ( "the boys getting loose"), or at least like my husband does
. Keep the fun, and good luck!
