I'm just an average-built white guy with an average-size 5" cock.
That's very unfortunate. But, you should take comfort in realizing you aren't alone. Most men, by definition of the average, are about average.

My sexy latina wife is 5'2", 110 lbs, has 34c breasts, a heart-shaped ass, and has a huge sex drive I cannot control.
Wow! What a pistol. You should be profoundly grateful such a red-hot woman condescended to accept your marriage proposal.

Since I cannot keep my wife satisfied, she goes out and fucks other men.
Hm... I see. On the plus side, your wife's realization that it is her privilege and prerogative as a married woman to date and fuck whomever she wants while expecting you to remain faithful as her cuckold, and her acting on this realization energetically, that is probably saving your marriage.

After coming home from an all-nighter [with a lover,] she sits on my face and forces me, under her skirt, to pull her lacey thong panties aside and drink her BBC seed.
Indulging herself in the pleasure of queening you after her trysts is customary, of course, for a woman like your wife. See:
The Fine Art of Queening
One has the impression you're accustomed to this, so that's good. You might consider asking her permission to increase her queening pleasure by purchasing a chin dildo for you to wear while she's riding your face. See, for instance:
Chin Dildos (“Accommodator”):
The Accommodator Chin Dildos, Face Dildos, Head Dildos, Facial Dildos
You might consider further increasing your wife's queening pleasure by also asking her permission to purchase suitable queening furniture. See, for instance:
Queening Furniture:

Her panties are being constantly destroyed by her obviously hung men.
If you mean literally destroyed, that could become expensive. Mac has given you some good advice for minimizing panty expense.

My wife constantly humiliates me. What should I do?
I suggest joining the "Humiliatrix.com" site — but not for very long, since it's a pay site. Several months or so of reading it daily... ask your wife for guidance on how long each day to read this site, so she doesn't become displeased with you... should be sufficient to help you become more accustomed to her constantly humiliating you, and accept it as normal. This is an important goal. When you become adapted, finally, you'll appreciate that your wife's humiliating treatment of you is free.
