The first thing to decide is whether there is anyone in your family or any of your friends that would cause a problem if they found out you were doing porn. Because, they WILL find out at some point. If it's a problem, don't even start, seriously.
The issue for men in porn is usually one of their expectations not meeting with reality. In straight porn, many of the guys don't even get paid, because there are so many that want to do it. And typically the women are the ones who selectively introduce the (new) men to the business. So, unless you're dating a porn actress, you're not going to break into that end of the business. That leaves gay porn. A lot of straight guys will do this, supposedly for the money, but there's not a lot of money in it. Gay guys do it too, and most of those I've met are into the fantasy aspects that it helps them realize in addition to some money.
To give you a read on the reality, male porn actors get paid 3-5 times less than female porn actresses, so on the whole, they're making between $50-150 for amateur stuff. Even professional, well-known gay porn actors are only making $100-300/day depending on their role and previous popularity.
For nude photos, you're looking at getting about $1 per photo that's actually used. An hour-long photo shoot will probably generate 300-600 photos, of which maybe 1 in 10 will be usable, so you're getting $30-60 an hour. Of course the better you are as a model, or if you satisfy some special requirement, the more likely the photo session will result in a higher usability ratio, and therefore the photographer will be willing to pay you more. Most new nude photo models (male) are offered somewhere in the neighborhood of $25-35/hour for a two hour test shoot. If you show up on time, are cooperative, have a good percentage of shots be usable, and are willing to come back consistently, you've probably got a good side job for pocket money, because most models flake out after one or two sessions, don't show up, or otherwise are a hassle for photographers.
One of the big things for you though, is to make sure you're comfortable with the photographer before you sign up for a session. Go meet them, ask the questions that are hard for you to ask, take 1 or 2 quick photos so they remember who you are (don't have to be nude, but this can also be a test to see if you can take your clothes off when it comes down to it). Schedule an appointment, and then stick to your appointment. It can be fun, but you have to do it because you enjoy it, not for the money. If you're not having a good time, the pictures will show you're not having a good time, and nobody wants (to pay you for) that.
If you've got a buddy who is handy with a camera, you can usually sell your photos to a web site that features nude male models for that $1 per photo they select that I mentioned earlier. It doesn't sound like a lot, but the economics work out that way, figuring that your work or their work, you're getting about $30-35/hour if you're shooting a lot of pictures to get the good ones from the bunch. If you're not in an urban area where the photographers are working, this may be an option for you. Video pays more, but then the quality and work demands are higher too.
I've been working with nude models for 8 years.
