Is it normal to feel this way.....?

i'm single; kind of a built muscle guy. i feel uncomfortable when i hang out with my friends. 'cause i've noticed that almost all girls shoot more glances at me rather than my friend btw, most of my friends are not that into working out like me..i mean not built. therefore, i might get him jealosy of me. so, what i usually do when going out with him. i just try to wear not too fitted t-shirts to avoid any unwanted glance haha. sounds crazy right? is it nirmal to have this kinda toughts??i only wear tight when going out by myself to attract horny BBs lol!
