i think it's entirely possible that beth has never had a real orgasm.
we see beth's mental growth was stunted sometime in her young teens, possibly between age 12-15. she may have clung to the "masturbation is bad" mindset. look at her mom, she seems like a frigid old hen.
i think generally women don't figure out how to get regular orgasms until after age 20 (22 here). since beth was stunted, taught that touching herself was bad and then used as a sex receptacle for scores of men as a means to bring in cash*, it's got to really shut down the mental process of sexual enjoyment.
*i have no proof that beth was a prostitute for money and cocaine. it is speculation and theory

You can look at some leaked or posed celebrity partial or full nudes and see the genuine lust for tube steak. Have you ever felt that after seeing one of Beth's pictures?
There's old pics and a short video where Howard and Beth are leaving a party and Beth clearly had a few drinks (and maybe something for her nose as well.) As the reporters and paparazzi are hounding them, she takes control and basically looks like shes pulling Howard away from it all because she needs to fuck badly. She kissed him and tried to yank him back to the limo.
That was the only time I've see her look remotely sexual. But you can probably get pandas to fuck if you liquor em up and give em a few lines.
The reason Beth always has that insane smile is because she's so happy she hit the lottery with stern. She can't hide the fact she loves the cash and fame. Take away the cash and fame and there's no smile or Howard of course.
