On the contrary my friend, guys can be faithful and that simply comes down to meeting that special someone which you can see yourself waking up to for the next 30+ years.

I can't speak for other males, but I can say that if I met someone which I consider would be the one (of course the feeling needs to be mutual with the other person) then being faithful isn't really hard.

Just have to meet that special someone first which is certainly the hard part and another problem comes about because we do live in a superficial world, and trying to find emotional and physical chemistry is quite daunting!!!
