first Welcome,

anal play could be great if done well - just one needs to be carefull with it.

for starters check this threads:

Butt plugs and

Anal sex

Than do spend some time googling - there is lots of pages out there. Do not avoid gay pages - be it female or male the anal play is similar - and some of those guys have lots of experience with it.

How ever you proceed with this, take it slow, and make sure you are enjoying it! good luck.
