I think if it was really hurting/harming her she'd have let you know by now and would not be so willing to engage. I've only had some slight bleeding as an effect but that was only a problem right after the fact and ended pretty quickly.
Maybe do some research on gay mens websites? I don't know. I know gay men (who are quite open and willing to dish details) and I've never really heard them say anything about bowel issues as long term effects.
So, so you think you can tell Heaven from Hell,
blue skies from pain.
Can you tell a green field from a cold steel rail?
A smile from a veil?
Do you think you can tell?
And did they get you to trade your heroes for ghosts?
Hot ashes for trees?
Hot air for a cool breeze?
Cold comfort for change?
And did you exchange a walk on part in the war for a lead role in a cage?
