Coffee and sex, they have more in common than you may think. Both are great ways to kickstart your morning. They both give you life (some more literally than others) and can make you a little sleepy if you’ve had too much. And they’re both things that people are really into. Like, really into. Unfortunately, though—and contrary to what the internet would have you believe—only one of them has a competition full of goofy outfits, weird toys, mood-setting soundtracks and confused onlookers.

Even still, coffee and sex may just be two great tastes that taste great together. According to an actual doctor, drinking coffee before sex may intensify orgasms.

Brought to our attention by the New York Post, the rousing suggestion comes from Dr. Karan Rajan, a surgeon with the National Health Service in the United Kingdom. Known as Dr. Raj to his 5 million+ TikTok followers, Rajan answers questions and gives advice from the perspective of a medical practitioner. For this video, which has already amassed 2.2 million views, Rajan is responding to another TikTok video claiming that coffee before sex can intensify the orgasm by 50%.

The answer depends on the amount of coffee. According to Rajan, blood flow is the key consideration here. “The better your circulation, the more flow to your erectile tissue,” he states. “Thus, the more likely you are to reach states of arousal that sets the stage for a great [orgasm].” In smaller doses, caffeine works as a vasoconstricting effect, which narrows the blood vessels and decreases blood flow, which isn’t what we are looking for here. But in larger quantities, caffeine has a vasodilating effect, improving blood flow via widening the blood vessels. More coffee is key.

Rajan further bolsters the claim with a 2005 study in the journal Pharmacology, Biochemistry, and Behavior whereby female rats who were given caffeine were found to increase their engagement in sexual activity. Per the study, the results “suggest that the effects of caffeine on female mating behavior may reflect an increase in both sexual motivation and locomotor activity.”

And in case you were wondering, Rajan has given everyone the go-ahead to take part in a little empirical testing of their own. “It does seem like a fairly benign experiment, so do whatever you need to float your erogenous boat.”

So next time you and your partner have finished your morning coffee, consider engaging in some rigorous science. Doctor’s orders.
