Spirituality is making me anhedoniac!

I only find pleasure in working on my goals and achieving something every day. Female bodies don't seem much attractive anymore but out of habit I masterbate after every 3 days just for the sake of it. I don't even get an orgasm after ejaculation. It is bland. Boring. And I have lost a lot of attraction for all the mainstream things. This all have started happening after I did 10 days Vipassana Meditation Course. Everything feels empty. I only find excitement in my work and time spend with close friends. Any thoughts? I am worried about my anhedoniac sexual activities as I am still in my 20s
