There is a shoulder press machine at my gym where I can lift the whole stack, which is 205 (about 95 kg) but I can't lift anything like that with a barbell.
Just goes to show ya, everybody's different. I would have thought that a woman who is 5'10" and 120's would look painfully skinny. You look amazing. "It's the muscle."
Since you can't do anything about it, I'd just point out that there are an awful lot of short girls (5'0" to 5'4") who don't particularly appeal to taller guys. They need love too.
Cute, I am 5'10" and 245 with a big belly. I am also very strong, but you wouldn't pick me out of a lineup as being an athlete. My wife still loves me ;-)
