A Ha !!!
I know where latex came from now.
Give me a short while and i post picture of what i did.
Edit: ok i got sharp pointy knife and poke skin and latex came out, i show again with knife in fig but had to take picture fast before knife fell out.
Sal i think some type of bug is stinging or biting into some of your figs.
Also the mark on top of the fig pictured happens when leaf rubs on fig and mars it over time.
