Recently i have not felt a healthy sex drive and i've had trouble with sexual performance. i'm in good shape and exercise everyday. what can i do?

I hope you get lots: I'm looking forward to you getting other replies - but let me start. Have you thought of considering it as a natural phase - like the seasons or the moon. To never ebb and flow is a bit unnatural. At your age, I'd almost expect your sexual expression to be maturing from youthful volatility into a deeper complexity. Try some non-judgmental curiosity to expand definitions of sex. Best!

Get rest get checked: For a male in your age range, lack of sleep and rest, and emotional or relationship stress are major threats to sexual performance. Is this a new problem, or something that's been there for a while? See your clinician and get a testosterone level as part of your workup. Hope that helps.
