I like being picked up by guys even when we're not making out, my guy friends pick me up all the time and I love it. I like it even more when I'm making out and a guy picks me up. I don't weigh that much but when a guy just effortlessly picks me up and keeps me up for awhile I just can't help but like cause I'm just like, "omg he's so strong, I love it!"
My girlfriend enjoys it, and I enjoy doing it to her. As a tip for the guys who may not be as strong, have the girl wrap her legs around your waist to help support her. Sometimes it's fun to do anyway.
