Low libido and painful sex

Hi ladies, I've been married to my husband for almost two years now and sex is still not enjoyable for me. It's painful and at its best it doesn't hurt but it's more numb than anything. I never had sex before marriage and I've been told by the doctors that either my vagina needs to just get used to it or that my husbands "manly part" may just be too big for me... But I'm reaching my wits end. I've tried lubes, more foreplay, etc but nothing has really helped. Part of it may be due to the fact that I really don't have a natural desire for sex. I've also wondered if meds I take affect me (for depression and anxiety). Doctors said maybe but maybe not... I love my husband and I'm attracted to him and want to be with it, but it's like my lady bits haven't gotten the memo. It's taking a toll on me and my husband, and ultimately our marriage. Any advice/people experience something similar??
