Tmi maybe?

Over the past 3-4 months I have noticed a change in my clitoris/labia area, it has appeared to me that it has gotten what seems to be bigger, more wrinkley looking and the lips are more folded looking down more towards my vagina opening.

I have only been having sex for a year now, and have been with the same guy however he has had different partners and did had unprotected oral sex and protected sex.

Should I be concerned? Could it be a std or is this completly normal?

Any advice please!
