Whataboutism at its finest

Here's the best way I've heard this answered: does it impact your life negatively in any way? And if so, would cutting down help that?

Best way to test that is to stop or reduce how much you do it for a while. See if anything improves or changes. Note the difference. And then ease back into it.

But shortly, no, once a day is not too much or too little. Everyone is different. So unless it's keeping you from being sexually fulfilled or distracting you a lot or whatever, have at it.
