I told my gf when I started and it’s only been 5 weeks, she said had I not told her she was going complain (feels different now) and she also said she was happy with the size before I started so we decided I will only stop once it’s a problem.
She also said it feels bigger but nothing major which is great because it means I’ve gained in 5 weeks. I previously had to stop exercising because I was hurting my ex because of girth and up until that point I never really paid any attention to girth.
