Thank you for all the interesting replies, guys!
Day Two is at a close and I'm feeling great. There have been a few tough moments. Last night I had a very vivid sexual dream. I get these maybe three or four times a year. I woke up hornier than I've been in ages, but I was able to laugh and go back to sleep. It felt very satisfying to be able to continue my sexual thoughts throughout the day. Usually masturbation would stop them dead. Now they build up and I'm aroused more often. I don't find it frustrating - rather I'm amused at my body's desires.
I'm excited about going through this challenge. It's something I didn't think I could do. Even getting past two days is enough to give myself a pat on my back.
People around me have made comments about it being pointless and I just should get it over with. That just inspires me to keep going with this. I'm not going to let the chemicals in my body dictate what I will and will not do.
Good luck to everyone else testing their ability to take control of themselves.
