These fine ladies have done a very good job at giving you a breakdown of the cam business.
There's something that I'd like to share with you if you are still considering camming as a male(even though by now you may have decided to not do it)
I used to cam at Flirt4Free before transitioning to MFC, and the guys there actually did pretty well. They have daily contests held sometimes and they publicly make that available to members on the site, so on a day where there's a contest, they show the top 25 rankings sometimes girls and guys separatly, but most of the time they combine both sexes, and a lot of guys do very well on there actually, you can even go check yourself. Alot of guys have been the #1 earner of the day even. They even publish the most credits(which are like tokens there) earned ever monthly and the somebody on the guys side way surpassed the most credit earned ever in a month than the record on the female which would be found in the Hall of Fame Page on their site. He did over a million credits in sale and of which he's probably get anywhere from 20-30% cut or 34% at most if he's his own studio which I doubt. I don't know the guy personally but he's been on the site for 4 years, and he's half white half black. Aaron Best is his name.
Tricky things is, you've gotta be willing to do things out of your comfort zone if you aren't gay. You gotta be willing to do anal shows, use toys, role play and such, and keep consistent which is key to building your fan base.
Surprisingly, gay men are actually really good tippers, if you make an account on there for free(all they need is a credit card verification you don't even need to buy credits) you can browse around the models' profiles and you can click under "gifts" and see all of the tips they've earned for a given time(I think it even tracks as far back as when they started on the site) so you can see for yourself if you're curious. I think Aaron has made over 100k in tips in a 24 hour period, you can even double check on the site. There's another guy that's been in private for over 23 hours last month setting a record and he beat his own record by being in a 24 hour private over a couple of weeks ago I think.
Bottom line is, you gotta be Gay4Pay lol to make good money. There was a month long contest actually that was held this last June(like a miss MFC thing, but it was meant for the top ten models to win a trip), of which I worked pretty much everyday that month only took 3 days break, I came up at #6 that month, I was soooo happy, it was the most money I've ever made on that site! And 3 guys actually did more in earnings than I did, ,the #1 and 4 were girls, and #2, 3 and 5 were guys!
So it's entirely possible to make it very good money as a male cam model, you've got to have determination, a great attitude and be very open minded.
Hope this helps,
