You could be giving more money away and spending more time volunteering... But if you volunteered on top of your full-time job and gave all your money away, you might burn out, get into a depression, etc. There's some selfless sacrifices that you're not willing to make. Does that make you selfish? Is that bad?
So, if I got it right, you're saying that your sex life is something you can't temporarily sacrifice to slow the spread of a potentially fatal disease. You make me sick.
All the rest of your comments are just whataboutism. The world is full of moral wrongs, so your argument is that we should let it descend into a feeding frenzy. I shouldn't tell people they're acting selfishly if I've ever stepped on an ant. Completely absurd. Look in a mirror, bud.
