Are guys scared of older brothers when dating a girl?

Be honest guys! are you?

Ive dated a couple of men and they all seem to be the same way. I am the only girl and have 3 brothers.Two of them live with me and the oldest is married. Why is it though?..

Every time, like yesterday a guy I'm dating went through the back door and took me out that way, one thing for sure is that two of my bro's where by the front door. The only reason I find as to why is that they get scared to see my older bro's?
