If you follow the link, you'll find that it`s not really clear what they were used for.
Might be brothel tokens. Might be lewd novelty items, maybe for some sort of game (hence the numbers). Might be political satire - coins were symbolic of the emperor and/or state. Might be all sorts of things.
Similar Roman coins exist with a number from 1-16 on one side and various non-sexual images on the other (deities, famous figures, etc). Some sort of scoring counters for some sort of game, perhaps, in sets with different images on the reverse to appeal to different customers in different circumstances. Maybe.

If you go to Paestum or Pompei in proximity to some brothel you can find very explicits signs ,like penises instead of arrows, directly carved on the stones on the road and some sexuals "graffiti" too. Well, is not strange if you think that Pompei and Paestum were famous during the ancient roman period as holiday cities. Something like the modern Las Vegas.
