Religious people fixate on denouncing homosexuality , and homosexuality being a sin, yet they have sex without marriage. You're fine sinning it seems as long as you're doing it straight. I see no one posting about quiting fornication. Ask yourself why that is? It's because this guilt you're experiencing is socially manufactured, me thinks. And we live in times where it is okay to direct your insecurities towards the homosexual segment of the population and their homosexuality, rather than work on your own spiritual lackings.
Before you decide what to do, careful not to waste your youth and life mirroring social expectations.
