Not something I want to admit to anyone IRL, so hoping some Mumsnetters can shed some light on why my bum crack has become so massive!! Over the last year I’ve lost 4 stone. My starting bmi was 29, it’s now 20. Obviously my body has changed a lot, mainly positively, but a not so positive change I’ve noticed recently is a much wider bum crack! When I’m playing sports and doing lots of running around I can literally feel the wind going up it, it feels like the left bum cheek isn’t even making contact with the right and they’re permanently separated by pretty sizeable gap. Before I lost weight there was no gap, both cheeks sat next to each other skin to skin. I feel like I have a baggy butt now and it’s a bit disconcerting. I’ve done strength training throughout my weightloss and have fairly firm glute muscles and no noticeably saggy skin, however my bum crack is noticeably wider even to look at. It’s making me self-conscious. Is a wide bum crack just part of being slim if you have a certain body shape? Is this normal and I’m just not used to it? I really don’t like the feeling of having a wide crack, this is going to sound weird I know, but it feels like the inside of my body isn’t protected enough or I could have an anal prolapse at any minute 😬
