Semen Toilet Plume

Hello,
I do have an OCD regarding semen contamination. Before I was able to directly ejaculate into the toilet bowl, thinking this was a very clean way to dispose of semen. Then just flush.
However I only recently found out that when we flush the toilet small particles of what is inside get in the air, landing on everything in proximity to the toilet.
Now I am disgusted so much by myself, for doing this and I am not sure whether it is okay to keep doing it this way.
I close the lid now, but it is not air tight, so stuff still comes out.
Should I just ignore the semen in the toilet landing on me and everything nearby? Are other guys ejaculating directly into the toilet bowl and then just flushing?

I feel moral obligation to make sure no semen lands on anything.

Thank you

In public places if u "have to" use the bowl
for whatever reason y don't u flush it a few
times and even get toilet paper or towels to
wipe and cover the lid. I know I have never
sat on a bowl in any public place for the last
at least 10 years. If u r having this problem
at home it is only ur semen. I hope ur not
having a prob with it.
