Is it normal to cry seeing women (as a straight man)?

Is it normal to just see a (cute, more often than not) woman and feel sad? Like even if she isn't related to me in any way (ex, current gf, nothing like that, just someone on the internet)? I've even teared up at times just seeing them. And I don't even want to get started on how I feel when I look at, or just stand in their vicinity in real life... I feel physically tense, like my muscles (calf, etc.) tighten up involuntarily, and I get extra conscious of myself, and I can NOT look at her straight in the face. All this is on top of feeling sad seeing them and I just want to get away somewhere alone, preferably my own room and, idk, calm myself down. And after that, the sadness takes over and at times I tear up.
