I trained for a while with a Ladies team (I'm not out at school and a lot of pupils train there as well, with both the men and women). I've had to stop now simply for logistical reasons of getting there, but I assumed that I wouldn't be able to play rugby again at all once I was post-T because I'd not be able to play with the Ladies team, but it would be too dangerous to play against men in a Mans team while being FAAB. This might not be a problem for you, but for me at 5"1' and under 8st playing against women my size puts me at a weaker position than them dispite being stronger than a fair few of them. Then again, it might not be a problem in any less serious clubs.
I'm from East Anglia, the other side of the country, so I can't really help you on which clubs, sorry.
(BTW, good luck for Wales first match in the 6 nations tomorrow.)
