I'm in a pickle

My girlfriend and I used to participate in threesomes and more. She has been ill the past few years and can't do those things any longer. I don't want to leave her to fend for herself, so I set up a glory hole in my garage (a door with a hole in it for guys to get orally serviced.)

I feel terrible lying to her but I've had over 100 guys in the past three months. Most of them are married and come back for more.
