Hi there! To preface this, I am 18 years old, and I am a 100% virgin, I've never had sex, and I've never masturbated. I have primarily been a pad user throughout my teen years, but I have used tampons in the past. I bought a cup because I just liked the sound of it? How there's no chemicals and it's non absorbent, that kind of stuff. My problem is, whenever I go to insert it, everything down there kinda closes up shop and gets tight, and it's borderline painful. I've researched kegels and have tried to relax my vaginal muscles but nothing's really helped. Do you have any tips?
