Lunette cup

Ja

Okay I bought this thing months ago. I tried and didn’t like it. Now I’m trying again. It’s the white one. I think I got the hang of it but the tail thing stick out. Meaning not all the way but it’s enough to bother me. If I’m doing a workout and I teach yoga and Pilates I can see the tail TMI sorry lol. But do you think I can cut meaning trim it?
