Dating after prostate cancer

Anyone have any advice for a gay man on how to date after having prostate cancer. I'm currently in treatment with Androgen Deprivation Therapy so need to use Viagra for anything to happen, and also can't have orgasms currently and, I'm told, once I'm able to there will be little to no ejaculate (I had radiation therapy). I may need to stay on Viagra forever going forward which would remove any chance of spontaneity.

Should I just put this information out there up front on dating apps so those who can't handle it can ignore me or is it something I should wait until things are going well and then bring it up?

Any other gay guys in this forum? Would YOU date someone who had prostate cancer and some ED issues? You can be honest.
