7 signs that you have sexual chemistry with someone

• Sexual chemistry is an important part of a relationship. 
• Often times you can tell you have sexual chemistry with someone before engaging in physical intimacy. 
• Both laughing together and certain body language clues could be indicative of sexual chemistry.

We've all been there. They're sitting across from you looking you deep in the eyes, head slightly turned sideways, with the corner of their mouth curled into a smirk. You say something funny (not that funny), and they laugh all too easily. Chances are you have sexual chemistry with this person. 

"When you feel a magnetic pull or spark towards someone when you're not engaging in physical intimacy, this is what we call sexual tension,"Rachel Hoffman, LCSW, M.Ed., told INSIDER.

Though there's a good chance you're both feeling it, there are obvious signs that you have sexual chemistry with someone you're dating or seeing casually.

They make eye contact with you.

When someone makes eye contact with you, that's a key sign they're attentive and interested in what you have to say. Eye contact with someone who you have sexual chemistry with is slightly different. "If you look into your date's eyes and feel like there's a kindness behind their eyes, that's a sign," Hoffman said. "They'll have what seems like a sparkle in their eyes."

You feel physically drawn toward them.

"You may be sitting next to someone and feel drawn to them," Hoffman told INSIDER. "You want them to touch you and kiss you." 

You can't keep your hands off each other.

You're out to drinks and you can't keep your hands off of each other. It'll be more subtle — he'll put his hands around your back when he's talking, or maybe he guides you through a crowded bar, Hoffman said. If he reaches for your hand or puts his hand, then you can almost guarantee that he's into you.
