Fans of porn usually look for something different, but often what you find may be unique, but not necessarily good. MaleSuperSite is actually not that super, although I guess it is unique in that it covers both gay and straight content. Let's be clear, it's not a bisexual site, rather it mixes all-male gay porn with straight and lesbian hardcore.
There isn't any main content here, however, which makes sense since this content blend doesn't really work, like say peanut butter and chocolate. This site actually offers a bunch of links to content on other sites. There is no attempt to mislead you, since the site calls itself a mega-site from the get go. However, examining the links does raise a few issues.
The homepage focuses on seven gay reality sites. That provides a significant amount of content as they offer over 530 episodes of usually mediocre-looking videos and regular-res galleries. I say usually, as these are feed sites, which used to offer streaming-only content.
However, five of them give you superior-quality downloadable scenes. You can download 24 in the first month, 48 in the second and then all of them become available in your third consecutive month of membership.
Otherwise, you will fin another 16 other gay/tranny feeds. There are also 50 straight sites you can access. I find that a unique, if not necessarily an inspired move. The hetero links are the same idea as the gay ones, some are streaming-only, while others limit downloads until the third month.
I have seen hetero sites with some gay or bisexual content, but never a gay site with more straight content than gay. The straight sites may sneak in the gay smut for the curious, but most gay men aren't shy if they want to check out naked women.
Since it does not mention the straight content before signing up, it doesn't seem really designed to attract bisexual men. It is not clear, who the intended audience is here, but the limited access to downloadable content in the first two months, further limits its appeal to whomever.
