Coming to terms

I think I’ve finally figured it out. I think I am asexual and feel so conflicted. I have never really enjoyed sex but always wanted to be in a relationship and feel loved. I’ve had many partners and would have sex cause “it’s what you do” in a relationship but it never did anything for me. Fast forward, Im now married for 8 years and have a 2 month old baby. How on earth can I ever tell my husband??? I use to not really care about sex and but still did it for my partner, and then I began to struggle with sex and really hate it.. It started with making him wait days, then weeks, then months.. part of me thought it was a part of depression/anxiety but I just don’t think that’s it anymore and I feel I am asexual but I guess I just don’t know much about it. Regardless if I truly am asexual and have discovered this about myself I feel horrible having to fake this for the rest of my life from my husband.. he would never ever understand I don’t think.. and if he knew I have never enjoyed this for 8 years.. I think it would crush him
