How big is an ovulation egg?

As a dominant follicle is selected and grows (days 6–9 of the cycle), estrogen begins to spike (10). A follicle becomes dominant at about 10mm in diameter, and typically grows to be about two centimeters in diameter (and up to about 3.3cm) (14–17). That's about the size of a grape, or a hazelnut with its shell on.

Can you run out of sperm?

No, you can't run out of sperm. Your testes are always making new sperm, which means you'll have a constant supply even if you're masturbating a lot and/or having sex every single day. Having said that, it is possible to have a “dry orgasm”. This is where you reach a sexual climax, but don't ejaculate any semen.
