Vagina question

Hey ladies! I have a question for yall. Okay the other day, the very entrance to my vagina felt "different" and I did the mistake of telling my husband. And now he's super worried and worn touch me unless I go to the dr however I don't have insurance and don't have the money to pay for something that's nothing. Okay. The very entrance feels a bit tighter and partially covered by a rounding kinda hard (not very hard) tissue. I'm not sure what it is. Everything "looks" normal. Any idea of what it could be so I can ease the mind of my husband? It's right in front of my public bone kinda
