Both, I think its MORE age than a sex difference.. I take as many deer as I legally can in Ohio. One buck for the whole state.. and a WHOLE lot of does. Both sexes, depending on age, can be tough. Timely field dressing and hanging time are a factor.The proper cooking techniques help out as well. I shot a HUGE 10 pt buck one year, I estimated his age at 4-5 yrs. The back strap of that buck was one of the best I ever ate... shot an older HUGE doe the year after after that.. she was fairly tough, but still tasty! I butcher my own deer...so I select my own cuts of steak. Depending on the age of the deer is how much steak I get.. for example: an older large Buck, front legs...summer sausage. Back legs...summer sausage or jerky. Neck meat.. stew or roast. backstrap and inner loins are always steak on ALL deer. For a younger deer, I would cut the back legs into steak. ALL my excess " waste" is turned into summer sausage or snack sticks depends on what I wanna do at the time. I try and not waste much meat at all and by the time I'm done I have a pile of mostly bare bones..I know I got a little off topic..
