I think that, in general, more men pay attention to me now - at least when I'm dressed up, which is kind of rare.
Overall, though, strangers seem to be nicer and less likely to be dismissive. Also, in the past it seemed to take professional colleagues a while to warm up to me. Once someone really got to know me I was taken seriously, but it often took a bit of time to get there. Now it doesn't seem to take as long; I seem to have more credibility out of the gate. That goes for both men and women.
My husband met and married me when I was 220 lbs (give or take 10 or 15). He's happy that I'm much happier with myself now, and I think he likes the way I look, but I don't think it makes a big difference to him either way. Nothing about our sex life has changed.
It's weird in some ways to read the posts from others about how they went from being invisible at a higher weight to someone who gets noticed at a lower weight. I understand it, but in some ways I feel the opposite. I felt like I stuck out (in a bad way) when I was at a higher weight, but at a lower weight I blend into the crowd. I just look normal now, just like any other person you might see walking by. That's one of my favorite things about being thinner; I feel like I don't stick out anymore, and as a result I'm so much less self-conscious. I used to be hyper-aware of my body every minute when I was out in public. Now I hardly think about my body at all, and it's a relief.
