Why is the blood supply screened for syphilis? can y0u contract syphilis through contact with infected blood during sex?
right...lucky for women.
yes.
woman receiving oral sex then is not at risk of anything w/o lumpsor bumps then, right?
however, a woman performing has a chance of gonorrhea and possibly others?
She can get gonorrhea, chlymida is not a concern for oral sex. Now the risk is low but possible.
Here are the risks both ways:
Giving to a man: Gonorrhea, Herpes and Syphilis
Receiving female: Herpes and Syphilis. (without a bump on his lip probably not a worry for either one of these)
Oh, but a woman who goes down on a man w/o protection CAN get gonorrhea or chlamydia in the mouth that way, right?
Because they are not passed from a man giving a woman oral sex. Just the nature of how they are passed and oral sex on a woman is just not a risk.
Why are Gonorrhea, chlamydia and HIV not risky for me to contract from thes activities?
The only small risk you had was syphilis and herpes and both of those risks are small. Syphilis result is conclusive 6 weeks after and herpes is 4 months.
