Is it ok to masturbate with testicular cancer?
I wondered about testicular cancer and masturbation, too. I haven't found anything about this specifically (though there are lots of opinions out there about masturbation causing and/or preventing testicular cancer!), but I can't imagine why it would be harmful. Again, I don't know for sure.
If you like to use lotion, though, I'd make sure it's nontoxic. No reason to add harmful chemicals when you're fighting cancer.
I'd also ask my doctor to be perfectly sure that it's okay. Don't be shy! I bet your doctor has been asked about testicular cancer and masturbation before.
