Is this shyness or anxiety or anything else?

So I have this weird feeling pop up at times. I am not scared of people, occasionally maybe if the groups are large I take a while to warm up. I can comfortably talk to a stranger and give speeches in front of a crowd. I have my moments where I might be scared to feel judged but I think that is normal and certain parts of it I attribute to my life. However, ever since I was young, I would feel extremely uncomfortable around certain guys in certain context. I would be scared to dance with them or get close to them. I have guy friends. But when I hear someone talk about romance or someone initiate any interest I immediately feel very uncomfortable (irrespective of whether I like the feeing or not). I cannot make eye contact and not admit what I am feeling. It is mostly specific to guys? Is it shyness?
