My understanding is that there is a 1% chance of longterm effect on sexual function in male with a pelvic dissection. I have heard of some men banking sperm before surgery because they wanted to have children in the future and there was a small percentage chance of that being difficult post-op. However, it is not a typical complication. What did your surgeon say?
With a colostomy you can wear a "stoma cap", which is like a very small colostomy bag, temporarily. Another option would be to stick with your usual bag and use an "ostomy wrap" (a stretchy band, basically) to hold it flat against your body. Yet another option is not to do anything special about
the bag -- you might be surprised how well this works (it did for me). Hope those search terms help you find more info
