I just got back from my second trip to see Master! And my goodness, we had sex a lot. Much more so than my previous visit, if I remember things correctly. Not that I'm complaining - far from it; I was the one who initiated a good portion of sexings.
On several occasions I was struck by how damn horny I was. Usually, I'm good with one go-round, but this time I wasn't satisfied until we had sex two, maybe even three times in a row. Which is really bizarre, because even though I'm multi-orgasmic, usually by the end of sex I'm a quivering, incoherent mess. But during the trip I'd have a half-dozen brain-shattering orgasms in one session and I'd just want more! It was great fun, but it made me wonder.
At first I thought it had to do with the fact that I hadn't seen Master in a while. But the time between my first trip and this last one was much shorter than the end of the school year and my first trip, even though I was hornier this time 'round. So that wasn't it. It's possible that it was hormones, since I think my period started while I was there. (But I'm not sure, since my Mirena makes my periods - when I do have them - super light, and it's possible the teensy bit of blood was the side effect of lots of rough sex in a short period of time, lol.)
I think one of the biggest differences was the time of day we had sex this time around. My first trip, we usually had it at night - often past midnight, when I'm already tired from a long day of wandering around the city. This time, however, we almost always had sex after we woke up between ten AM and noon. Not only was I refreshed and rarin' to go by that point, but I've also noticed that I tend to be hornier around noon. Which kinda sucks when I'm at work all day, but is awesome when I have nothing to do but lounge about with Master. >:3
I'm not sure what it is that makes me hornier during the day. Is it the "taboo" aspect - sex is supposed to be a nighttime activity, after all - something to do with my sleep cycle, or some independent factor? My guess is the third, since we have more-or-less independent cycles for our other urges, like sleep and hunger and such. Why can't sex have its own cycle?
Other changes between my first trip and my second? Well, I went on a free-range diet, which means I'm essentially vegetarian now, and I started doing yoga almost daily. (Gawd, I'm such a hippy.) Maybe they had something to do with it, but I don't think so.
