According to a statistics done by German #Aerzteblatt only 51% of all German males are into giving oral sex (#Cunnilingus for straight and #Fellatio for gay/bisexual accumulated) while 56% are into receiving (#blowjob ) it. While for females it is even a little lesser, 48% are into receiving it while 45% are into giving it. As it seems, also lesbians are counted in here, but are a minor compared to straight females.
So far I can tell that there is no "disgusting" or "unhealthy" thing on giving Cunnilingus (in English, licking #pussy ) simply because I have done it a lot on many different women and so far no tongue or throat #cancer has happened to me. And yes, beside that, there is no "fish shop" down there for me.
I like to ask the whole #Fediverse about this matter. Is that true with you? Disclaimer: Do not come up with some religious-nonsense or other hatred/disapproving/other nonsense here. I'm asking for a Yes or a No and if so, please more details (being passive/active).
I guess you already received such mails, claiming being sent from your own email address (which are mostly not, check mail headers, then you will see it) and that the #attacker (scamming is a form of #social-engineering attack) has some "hot stuff". Most claim to have nude pictures from you being published if you don't pay, so it is also a #ransom mail.
As you already may know (or not yet), don't reply and don't buy coins and send them to it. I have traced addresses such #19rtEghbzbyBqmgJLBtUGd9VvVC1s2bKzR and #1NUFhwLSmJPnjBNyjtuFPje54UG9AH1Ruc to accounts where Bitcoins in value of 4000 to 5000 BTCs have been transferred to and from. They seem to push the (illegally obtained coins around over several accounts (I guess thousands of addresses since you can create "limitless" accounts).
Well, interesting to see how many people already falsely belief in such mails (I don't do) and that some other scare sites try to explain that these Bitcoin addresses are viruses (which they are not). If you think that sounds to weird, check your favorite search engine and enter the addresses there.
