Message: Stomach Upset After Anal
Anonymous: Help? What can happen after anal sex? I get my stomach upset but I don’t know why or how can I prevent it…
It depends what you mean in this case by “stomach upset”.
Anal sex can put air into your rectum and colon and cause you to feel a bit gassy and bloated as a result, but that is generally just a short lived effect.
If you were close to needing to go to the bathroom before having anal sex, the sex can move things along more quickly.
Certain lubricants can cause a negative reaction for certain people and cause diarrhea or similar. Similarly, some people experience such reactions from semen in the rectum.
I’ll need more details to provide advice for your particular situation.
