"Yes and no (surprised by reaction). I am very proud of my abstinence," McDonald said. "There was a time when it wasn't even in my vocabulary. I've lived on both sides of the fence. People ask me, ‘Is it for your religious beliefs? Is it for your athletic believes? Why do you do this?' I found it a little, wow, that people approached it and reacted to it almost the same as me saying, ‘Oh, I went three and a half years without food.'
"Like I said, I lived on both sides of the fence and I know what God says and I decided that's what I'm going to do because God says it. I've lived on both sides of the fence and now being on this side of the fence I just see that my life is better for it. I said I want to do this because God says it and after I did it I said, ‘This is, it's great. It's good.' My life is better like this and I made the choice to stay this way and to keep it this way."
McDonald feels that abstaining from sex could actually help him in a fight because it will keep him mentally focused and he could use all that pent up energy to deliver a crisp performance inside the cage.
McDonald is set to fight Urijah Faber in the co-main event of UFC on FOX 9, which takes place Dec. 14 at Sleep Train Arena in Sacramento, California, so time will tell if his sexual abstinence will help his fighting performance.
McDonald's approach to sexual activity before a fight is apparently the exact opposite of some other notable fighters, including UFC bantamweight champ Ronda Rousey.
In a USA Today Sports report, Rousey said she has as much sex as possible before competition.
"For girls, it raises your testosterone, so I try to have as much sex as possible before I fight," Rousey said.
Rousey explained that her training regimen depends on whether she has a steady boyfriend or not.
"I don't put out Craigslist ads or anything," Rousey explained.
So basically it all comes down to a matter of personal preference. Some athletes will take Rousey's approach, while others will be more like McDonald.
Both are talented athletes, so there's no real definitive right or wrong way to go about it.
