There is always an STD risk, IIRC ~3% per year for condoms, which accumulates each year, always increasing, never decreasing. So the probability that your condom does not fail in any year is 97%. The likelihood that your condoms don't fail for N years is (0.97)*N. Odds of "no failure" for 10 years is ~74% and for 20 years ~54%. Not so great. You're looking like a fuzzy STD taco -a high risk matchup with no gain. Your gambling friends seek out younger, safer partners. [And that's part of what they're doing, isn't it? After all, studs can calculate probabilities too.] And that's just for condoms. What you're describing is not "skill" but a peculiar form of addictive gambling. And to top it off, there's always the "Lorena Bobbit" factor: a mate slices and dices b/c you gave him/her an STD.
