My favorite thing about my girlfriend's (25f) weight

I asked my girlfriend (25f) what her favorite thing about my weight is, and she was very kind and said that my (22m) weight doesn't really matter in terms of how she sees me but that her favorite thing about my fat is the extra squish at the bottom of my stomach. She said that it makes our sex more comfortable for her because even though I'm obese, there is still extra squish that means I'm not touching her with my body. She said these things really meant nothing to her and all she cares about was that we're happy and able to be intimate.<br><br>I think about these things every single time we have sex on my back. I feel like her weight is a burden or that she feels like that about me. I think about how my weight is affecting her or if there's squish for her to be comfortable. I feel guilty that I could be hurting her hip by putting my weight on her, and it's affecting my confidence about having sex with her. When I hear her moaning, I feel like I'm hurting her because of my weight.<br><br>I've tried to talk to her about this, but she insists that she is happy and there is enough squish for her to be comfortable. I'm 5'10" and 245 lbs. and she's 5'2" and 130 lbs. I've tried talking to her about it, but she keeps insisting that I shouldn't let my insecurities define how I see myself. I've tried talking to her about it, but she keeps telling me to go to therapy. She says that because she's skinny, she's never had to worry about her weight, but I feel like she's judged me because of my weight. I want to talk to my girlfriend about what she likes in our sex but I don't want to ruin our night by talking about my weight.
