I was thinking about this thread yesterday. I was in a bit of a $$ low point once and wondered the same thing.
First, you certainly the main thing that is needed to make porn: a big dick. (By which I mean a really awesome, incredible cock though you may not care about my opinion since you are a straight guy...but I digress.) You also have a nice body and you are interested in the work.
You've mentioned that you would like to do POV stuff, but how would that really work? To get any sort of decent footage you can't film yourself - you would need at least another cameraman if not 2 or 3. And you'll have to edit it all together later.
But my real question is, what is your business plan for your completed films? Do you have a distribution outlet for them? They will cost you something to make, and you'll need to recoup that money at least - making more than your cost is the goal. Do you distribute them online? Or through video stores? Are they DVDs that can be rented/purchased? Who are your contacts for mass producing and distributing your work? Or, if online, who are your contacts who are going to direct their customers to the web site where you will have the ability to make money? After all, you could post your vids almost anywhere - but most places you post will result in exactly $0 back to you.
It's an intriguing idea but I think that if you are looking for some quick cash...well, first of all join the club lol, I am also looking for some quick cash. But, it seems like making a lot of money right away from this is unlikely. If you get started now, and build up a fan base so to speak, you may eventually make money, but I can't see how you'll make a reasonable sum quickly.
My wet blanket opinion shouldn't stop you from trying it though!
