Yeah, Tena does now have gender specific pullups. I got a free sample of them from the Tena website I believe and I can tell you that you should fit in the mediums no problem. However if you want something that is very absorbent, these aren't going to work for you. From what I could tell, the tena pullups for men are designed to be an alternative, perhaps one step up, from the "guards", which are like pads and meant for slight drips.
Any heavy wetting of the tena pullups will cause them to leak and I doubt they could hold one full wetting. However if you're looking for something that's good for dealing with very slight drips, or you want something ultra discreet that you don't plan on wetting heavily, these will work for you. Just don't expect them to hold a lot, they don't.
