As a single person, I can tell you this: I don’t need condoms, because I’m not sexually active. Realistic or not, works for me.

Also, I would never carry condoms with me “just in case”. Similarly, I’m a nonsmoker and feel like I don’t need to keep cigarettes in my house, just in case that I would be tempted to smoke. Regarding the risk of STDs, it works perfect for me. I never worry about STDs, because abstinence protects me from those and it works better than condoms - it has 0% failure rate.

By contrast, condoms do have a non-negligible failure rate with respect to the transmission of STDs. Being an uncle who truly loves and cares about his nephew and niece, I would truly and sincerely never recommend them anything else than abstinence before marriage, and faithfulness to their respective spouses if they do get married.
In addition, I don’t get why the case of African people would be different from mine and my family’s. I would never recommend anything else to a friend, acquaintance, or even to a stranger from Africa. Abstinence for single people and faithfulness of married people to their spouses, works perfect and gives a 0% failure rate in protecting African people from AIDS. The programs based on abstinence and marital fidelity have been very effective against HIV/AIDS, in African countries such as Uganda.
