thank you for your reply. I did a self exam, when i fell inside my vagina, not too far in I feel something that feels round, kinda hard and ribbed liked in the photos, I believe what Im feeling is whats in the photos I shared and circled in red. is that what I could possibly be feeling? its not hard like a rock but its tough and isnt painful. i googled somethings and what I found is that its urethrea sponge/g spot??
