Diverticulitis & Gay Sex

I have diverticulitus, and I'm wondering if i have sex with a man (Anal) if that will effect it negitivly, or not at all.
The guy who I'm considering having sex with is my partner, been dating awhile, but we don't wanna risk doing anything until I know, so we have been keeping the "playing somewhat light"

So... If we have sex... What will/can/could happen?

Any time you insert something into the rectum and anal canal, there is always a risk of tearing, causing injury and possible introducing infection.

Be sure to stop any activity that causes pain or discomfort immediately.

More serious problems that may develop are:

- Abnormal connections that form between different parts of the colon or between the colon and another body area (fistula)

- Abscess (pocket filled with pus or infection)

- Hole or tear in the colon (perforation)

- Narrowed area in the colon (stricture)
