I was reading that karezza is good during a reboot. I am On day 19 of the reboot and I was cuddling with my friend the other day.. I couldn't really get a hard on. After reading the four steps of karezza I see that it is sexual intercourse ( even though it's gentle) so my question is how do you have sexual intercourse when you are not able to get a hard on? I getting a good strong erection was a result of karezza not a prerequisite. If someone can clear this up for me, it would be much appreciated.
