Some studies show that intense eye contact can actually stimulate sexual arousal. People like feeling seen and understood. Intense or prolonged eye contact helps people feel seen and can make them feel confident and even aroused. Not only can eye contact heat things up, but it can also make sex more intimate.
4-5 seconds To maintain appropriate eye contact without staring, you should maintain eye contact for 50 percent of the time while speaking and 70% of the time while listening. This helps to display interest and confidence. Maintain it for 4-5 seconds. Once you establish eye contact, maintain or hold it for 4-5 seconds.
Breaking eye contact can indicate that something that has just been said that makes the person not want to sustain eye contact, for example that they are insulted, they have been found out, they feel threatened, etc. This can also happen when the person thinks something that causes the same internal discomfort.
When girls see you and look down?
If she appears flustered, uncomfortable, or looks down, this may be a sign that shes not happy about you thinking that she likes this guy over you. If she didnt have any response or simply waved back vaguely, this would indicate that shes not that interested into you.
