Our senses can tell us a lot about our surroundings, and can also tell us amazing things about our prospective partners. Learn how to determine if someone is interested in you, as well as be more in touch with your own feelings towards romantic individuals.

Smell-
Our noses are designed for sex. Our sense of smell allows us to decide if someone is healthy, compatible with us, or a close relative. Pheromones of our relatives smell repulsive to us, which is a biological adaptation that occurred in order to prevent inbreeding.

Sight-
Our eyes dilate when we look at the object of our affection; this mimics the look of our pupils when we are having sex. If the black regions of your eyes get a little bigger after looking at someone, chances are you’re crushing.

While dancing, women with a long term partner and women who are ovulating send the most sexual signals, provoking competition in available mating partners. The way that people walk also can indicate health and sex appeal, as we tend to exaggerate our stride when people watch us.

Hmm baby, I like your symmetry. Our bodies are modeled to be completely asymmetrical but during fetal development and life, people become less symmetrical and are thus seen as less attractive. As a defense against bad breeding policies, we tend to avoid mating with people that share similar characteristics as us. These are classed “sister traits” and this mechanism allows us to avoid inbreeding.

Thought-
MRI scans of people who are in love reveal that there is a region of the brain that is specific to love. This is the place where dopamine is made, and one other area that is activated when you want something or are trying to win, either at a game or at romance. These two different brain systems regulate how we handle both goals and rewards.

Touch-
When we become aroused, blood moves from our organs to our skin: keeping us warm, flushed and with enough blood in us to get an erection, or to palpate our vaginas. This necessary blood flow will become apparent when you touch your partner’s skin. Are they hot or flushed? Either they have been dancing, drinking a little too hard, or they may be attracted to you.

Hearing
Our voices change in pitch when we are flirting and, in a study done by BBC.com, hetero-sexual men rated the voices of women who were using higher-pitched voices higher on an attraction rating, believing the women to be more likely to look attractive and be healthy. The heightened influx of estrogen gives an audible signal to the listener, and this happens when a woman is ovulating as well. Women, during their ovulation cycle, tend to have higher pitched voices.

The best way to determine attraction-
Relying on your senses can be fun, and even effective, however, there is one way of determining attraction that is even more accurate.

Come on out and ask! Chances are that this honesty will flatter the object of your lust, and even if they don’t like you in return, it’s sometimes best to know. Asking and being upfront may startle someone into telling you the truth, and if they don’t like you in return, it’s a lot easier to move on after knowing the truth.
