Not everyone has an enema - it depends how good you are at emptying your bowel naturally.
Not everyone has all the side effects - John had his RT at 8.30ish each morning on the way to work - he never needed to take any time off and he carried on going to the gym after work every day and rugby etc.
RT induced fatigue tends to kick in towards the end of the programme and linger for a couple of weeks after but it didn't stop him doing anything.
No urinary or bowel problems at all. You may not get ED but you are likely to lose your libido.
Breast swelling depends a bit on which hormones they put you on - you could ask whether you can have a shot of RT to the breast buds before you start on hormones.
