A guy with sisters is already equipped to deal with all of the horrors of “girl world.” He’s used to living with lots of girls and a girlfriend isn’t much different. He knows how to survive an argument and even how to do hair. A guy with sisters makes the perfect boyfriend.

1. He knows how to avoid a fight.

Most guys say stupid things without thinking about how a girl would react. A guy who grew up with sisters understands what will set a girl off and how to avoid starting an unintentional fight.

2. He doesn't complain (as much) about watching chick flicks.

He grew up watching "Hannah Montana" and "Lizzy McGuire," so he's much less likely to complain when you want to watch "Clueless" or "50 First Dates" with him.

3. He's used to taking lots of pictures and selfies.

Girls are notorious for taking lots of pictures and selfies, so he's already used to that when you get to him. He's always willing to take pictures with you and, sometimes, believe it or not, he even initiates the picture taking.

4. He's great at matching outfits.

When he shows up to pick you up for a date, or even when he's simply dressed for class, he always matches impeccably. After growing up with sisters who match all the time and who most likely pointed out when he was not matching, he's learned from the best and dresses very well.

5. He doesn't mind the smell of nail polish.

All guys groan at the smell of nail polish, except these guys. A guy who grew up with sisters is extremely used to the smell of nail polish around the house and, surprisingly, he doesn't seem to mind the smell even when you're painting your nails right next to him.

6. He isn't weirded out by your "time of the month."

Having grown up with two sisters and his mother, he's a pro at handling girls when they're moody because it's their "time of the month." He also isn't weirded out when he goes into your purse to grab his charger and encounters pads and tampons because he used to find them in the house all of the time.
