Can I get infected with STD by:
Tell the provider to spit on my cock and then cover it up to do CBJ?
Tell the provdier to give my cock a few licks with their tongue (not sucking it)
Me DATY the provider's with just my tongue light licking
Me DATY with my finger

but in practical terms, the activities you describe are fairly safe.

Yes for all of them in theory?

You can get infected by just about anything, at any time in this hobby... but chances are slim to none with the activities you describe.
Here... read up... suggest you also start to read postings on "The Erotic Highway" board where topics like STDs come up all of the time... Love Goddess is your guide there, she is nothing short of fantastic.

In each case you describe an encounter where some part of you connects to some part of them, or their bodily fluids.

A virus is capable of traveling from you to them, or vice versa and that's why I stressed "in theory".

Who knows, a sneeze could be all it takes too.

In practical terms, however, all the activities you describe have a very low probability of transmitting any venereal disease.

I have learned quite a bit from this board and the links to various  sites that discuss the health ramifications of various types of sexual activity.

I suggest you read them and decide on your own personal comfort level.

be infected with a disfiguring disease that will have you covered in open, festering, malodorous boils or simply corrupt into necrotic flesh that falls from your bones just by picking up the germ tainted receiver of a public phone.

go to www.medhelp.org and follow the links to the STD section. It is moderated by a doctor who also happens to run an std clinic. By far the best site I have come across on this topic.

CDS1, I have learned so much from this site and am thankful that you are sending people there also, Dr HHH really knows what he is talking about and has helped me ENJOY this hobby. Keep tellin people the truth!
