I feel ya, my family is african from western sahara personally so I ve never put on sunscreen nor gotten sunburnt, In my opinion the best you can do is expose yourself for durations under 3 to 4 hours, wear a hat with a round lid (cowboy for example) and wear long sleeve light clothing. Depends on where you live, but you should really have problems only when you get close to the equator during the summer. In my opinion, as much as it sucksm the alternative would be to use a cosmetic that might make you sterile through time, give you gynecomastia, lower your sperm count, raise diabetes and high blood pressure risks or worst case, cause neurodevelopmental disorders in future children you may procreate (adhd and autism spectrum disorders are known to have a link to it).
