Not even in heathen lands. By and large medieval warfare was very small scale and neither sieges nor battles nor armies worked that way.
Castles and towns were sacked only if they refused to surrender and lost(which generally didn't happen) and pillaging was generally regarded as a measure of desperation except for in major wars between two entire kingdoms(see: England v France) where pillaging was regarded as a legitimate demoralization technique(also a way of sourcing supplies).
Most wars, however, were not between two entire kingdoms but usually between minor feudal powers within Europe - usually over land disputes. As such wanton pillaging would've been discouraged(because the new lord of the land doesn't want to be remembered as "that guy that raped our daughters and butchered our sons").
Instead, the issue of sex in medieval times was resolved in many ways like the issue of supply. Medieval armies were followed by entire caravan trains sometimes larger than the army itself which provided a variety of services ranging from merchants selling food and supplies to prostitutes.
Yes, that's right, Medieval Europe features traveling troupes of prostitutes - usually complete randoms that got together on the spot but I would not be surprised if there were celebrities in this regard too. Like porn-stars except you get a chance to catch their syphilis!
Depends on where you're stationed. By and large the current figure stands at 0% and in an active war-zone it drops to negative numbers. For one modern, professional, all volunteer armies are considerably more disciplined(see: sanctioned, regulated and micro managed) and also most of the places they've been going to haven't had good pussy since the Ottomans.
Hence the birth of the (dis)honorable combat jack, a time honored tradition of all combat units everywhere. Sometimes combined with the humble combat dump for extra disgusting.
By contrast, I understand a lot of dudes stationed in Asia go home with VD but the Corps's apparently been cracking down on such excursions as well.
All the blue-balling might actually be positive for combat effectiveness, like gelding a warhorse - see: I read somewhere that sometimes they'd take a top-tier stallion bred for war, tempt him with some hot mare ass so he'd get turbo horny and, just before getting his bone on, snips his dangles off. Made the horse super aggressive, apparently. Can't imagine why.
On a semi-related note, today often times the way horses are usually bred is a vet will jerk a horse off into a bucket then divide it into (frozen)samples to sell to the highest bidder.
I wonder if they didn't have something like that in the middle ages, some poor schmuck who's entire job was to collect horse cum and some potentially even poorer schmuck who's job would be to grab it by the handful and jam it into a female horse's cunt.
Wonder if it would've been a male or female job, our modern sense might prefer female but with Medievals you never know. They had some weird fucking customs(like having another man touch your asshole).
Pic semi related because, as a lot of people know, the second and unofficial job of females in the military is deniable prostitutability. Unfortunately they never look this good.
