Need to tell someone.

I (22F) have recently been seeing someone (25M). We have a good relationship despite not being in a relationship yet. We were doing the deed last night on the couch and out of nowhere when I was on top he stood up, holding me like I weighed nothing and we carried on doing the deed. I’m not exactly overweight but I have had 2 children so I have some extra weight but the way he lifted me like I weighed nothing at all was incredible. I needed to tell someone😂
