Here are some surprising things that can boost her arousal.

Sure, there are obvious things a woman can do to indicate she's interested in more than just your personality, like finding excuses to brush up against you at the bar, and says: so what are you drinking, can I buy you the next one? But what about the more subtle signs that let you know she means business? the following are  five things that can  boost her arousal—and how you can take full advantage of each one.

1. Roller coasters. adrenaline rush!
Talk about being in the right place at the right time. Research from the University of Texas at Austin shows that people who have just stepped off a roller coaster find the opposite sex more attractive. The study found that symptoms of physiological arousal—like heavy breathing and increased heart rate—tend to linger without our knowledge after any adrenaline-pumping activity, intensifying perception of attractiveness.

Make your move: Luckily, you can harness the power of "excitation transfer" without hanging out at Six Flags all day. A simple Netflix binge at home can do the trick. Fire up your favorite, jump-in-your-seat horror movies—and keep some massage oil handy. Add some caring touch into the equation, and the bonding hormone oxytocin also blends into the mix!

2. Your dress shirt. She is seeing red. in a good way!

 In a University of Rochester study, women found men who were either wearing red or surrounded by the color to be more attractive and sexually desirable. Researchers attribute some of the connection to the historic use of the color as a symbol of wealth and power.

Make your move: You probably know where this one is going: Wear red! It's that simple,  Too bold for your button-downs? Consider making it the color of your boxers or briefs,"


3. Your dance moves.

A recent study in Biology Letters found that women consider large, varied, and fast movements like head-nodding and torso-twisting most arousing on the dance floor, because they signal strength, suppleness, and vitality. The study suggests women prefer "vigorous and skilled" males—and dancing ability perhaps signals physical condition. (Hey, I'll take the researchers' word for it!)

Make your move: Shuffling around with your hands stuffed in your pockets won't cut it. Learn to Salsa.
Take her dancing and don't be afraid to let go on the dance floor,  But you'll have to do better than the sprinkler: Take dancing lessons together, and allow the experts to teach you how you can best move together.

4. Your lack of deodorant.

Skip the cologne—NOT.....according to research from the University of California, Berkeley, it's your natural musk she's after. Scientists found that a pheromone in male underarm sweat causes a spike in women's levels of cortisol, a hormone associated with arousal and brain activation. The result? Your pit stains can improve women's moods and increase sexual arousal.
Are you kidding me..... I don't really buy this one.

Make your move: Work up a sweat—together. Plan to go for a hike,suggests Fulbright. If you go in for a hug and she complains that you stink, "it's a good indicator that you may not be the best match, at least reproductively speaking. But if she digs it, consider yourself very lucky.


5. Red wine. woman drinking red wine

If she picks a Cabernet on the first date, it bodes well for the rest of the night. According to a study from the University of Florence, women who drank one to two glasses of red wine a day had higher levels of sexual desire than non-drinkers. Researchers also found a correlation between moderate wine consumption and higher levels of lubrication.

Make your move: Drunk and sloppy isn't the goal, so keep it classy. "Invite her to a tasting at your local wine store. More than two drinks actually constricts blood flow to the genitals. Translation: Leave the box of Franzia at home!
