DNA and Online Search Finds Birth Parent

WTF is with people tracking down their birth parents. Genetics mean squat.
There are many diseases with a genetic component. Knowing your genetic history can be very useful.
A quick google search of the guys name after a google news search of the terms "sperm" "oral" and "child support"
"Sic Semper Tyrannosaurus Rex."
Child support is the child's right to receive support from his/her parents. So unless the child is of legal age to sign away their rights to support (unlikely at birth), any such contract can't really legally protect you.
A more likely contract, offered at at least a few places i've worked with, works more like insurance: if a claim for child support is made against you (the sperm donor) then the clinic will pay it off for you. The clinic then has contracts to further pass this risk on to their insurance carrier.

Human sperm can "survive" for about 48 hours at body temp. -- where "survive" means they're still swimmers. Beyond that, they are viable (for lab impregnation) as long as they stay hydrated and uncontaminated (i.e. free of bacteria, mold, chemicals, etc.) [It's worth noting, your sperm is very likely contaminated by the time it gets out of you.] The actual genetic material will be (forensically) intact for years -- I'm not saying you could make a baby from it.
As for "stealing" sperm... she'd have to get the "sample" within a few hours for them to still be able to perform naturally. Using sperm from a used condom simply won't work... pretty much all condoms made these days contain spermacides.
