Each Zodiac Sign has a susceptible spot. Whether that is a specific body part or a specific behavioral pattern, there is a way to address to it and stimulate their sensations.
The most sensitive part of the Aries body is the head. You may notice that Aries usually have a very noticeable and distinctive forehead. It is their Achilles heel. They are extremely sensitive with this area, so if you touch or try to feel their face, it will certainly not pass unnoticed.
If you actually want them to notice you, you should touch them there either accidentally or make an excuse and go for it. Be bold and impulsive about it, as they love this kind of behavior. Maybe try to kiss them goodnight on the cheek or even feel their forehead to check if they have fever. Try to keep contact for a few moments looking straight in their eyes while you do. They will be pleasantly surprised.
Another way is to attract their attention is by stimulating their brain. So in other words the same area of their body but on an intellectual level. They are suckers for productive yet honest arguments. A strong and passionate conversation could make them see you with a different eye. They love to engage in intense debates, so make sure you stand your ground when disputing with an Aries. It will definitely arouse their interest for you.
Do not forget to compliment a very specific aspect of their personality. It has to be something unique and special, something they have never heard before. If you manage to do that with your heart without becoming pretentious then you will certainly win their heart and make them feel special. Don’t forget to use cynical humor and plenty of irony as this is what stimulates an Aries the most on an intellectual level.
