Goto your local pharmacy. They should have a reasonable amount of condoms, lubes, spermicides / etc that you can use.
I'd rather be embarrased and buy a bunch of Contraceptive goods than be embarrased with a kid. Besides, Contraceptives are cheaper than the average 400k+ cost of raising kids these days
Btw, Spermicidal lubes seemed to have dropped off the market. Problem was people that used a lot of lube were having problems with irritation due to overexposure to nonoxynol 9. Add to that after it was disproved that nonoxynol 9 had anti-HIV effects and that it actually raised the risk of contracting disease (due to the irritation), the Sperm-lubes dropped out of the market it seems.
