What do exactly the majority od the ts girls provide?Also what is bbj and bbbf?

you are a little slow on the uptake, aren't you mr. tom smith? your questions were answered on the thread below....but i will spell them out for you anyway.

bbbj = bare back blow job (that means a blow job without a condom). bbbjtc means she takes it in her mouth.
bbfs = bare back full service. intercourse without a condom. if you are talking about a pre-op ts, it means anal intercourse without a condom. for the receiving, or bottom partner, it is by far the riskiest sex act for hiv transmission. there is also risk for the top partner, though significantly less.

nobody advertises or admits to bbfs, but it happens quite often. in my humble opinion, any provider who submits to the bottom half of bbfs is either:
a. already infected
b. desperate for money
c. living in denial of disease risks
d. really stupid
any provider who wants to top you bb is either in one of those categories, or just a horny mofo.

bareback oral is significantly less risky than anal or vaginal intercourse. just how risky is subject to much hot debate. read a providers reviews to find out if bareback oral is available... if you visit an unreviewed provider, you takes your chances and have no call to complain afterwards.
