I want to ask that it was my first time having sex at22 and ever since that day have not been horny or wanting more, and what birth control is best for preventing pregnancy?

Schedule a visit: This is an issue best decided after a full history and exam by your doc/obgyn. Your prior medical history or chronic medications may eliminate some types. Your desire to make it permanent/reversible factors in. Your ability to remember a daily pill vs periodic visits for injections would count. A copper IUD may be the simplest non-hormonal method but it is pricey & placement is uncomfortable.
