"Reasonably" is going to depend on a lot of things. Where you live, what sex options are around, how "picky" you are about your partners, the sex culture where you go, etc....
I've noticed a HUGE change in the number of loads I can reasonably get in a year since I got clean from my drug addiction. Both when I was in active addiction, and now, I've lived in Amsterdam with easy access to the darkrooms of several bars, movie theaters, and some major sex parties (although the two big ones with 500-750 men have closed down over the years). I used to go out twice in the weekend, and easily take 15-20 loads a night. Hell - anything less than 10 loads felt like I wasted my time cleaning out and my money....
Since I've gotten clean, I don't go out to the organized sex parties anymore, and not too often to the bars at night. I choose not to play with people who's profiles are too explicit about their drug use. And maybe I'm getting old, but once 2 am hits it's yawning that I'm doing and not opening my mouth to suck a cock! And, without the drugs to numb/kill the pain, my ass will end up getting sore and tired after 4 or 5 good fucks, and hanging out in the bars to let it rest just isn't all that much fun anymore....
But I'm still in Amsterdam where I could probably easily still be getting 20 loads a week if I wanted to. Not everyone is that lucky where a 25 minute walk gets me into the heart of the gay sex area. If you're in a rural location and the closest gay place is the public restroom down the highway, you might be lucky to get one load a week if you don't have a local fuck buddy. And not every city with a good gay bar scene allows sex there.....
