Is it normal that my only male role model is my older brother?

He is my half brother (same dad) we both are very close. We both were raised mostly by our moms .He's 4 years older than me (I'm 18 and a guy). I never liked my dad and he's been mostly absent in my life. So my older brother taught me how to drive, catch,fight, etc. Honestly him,some friends and my grandpa are really the only men I really like even to this day.
