Why do men get so sexually aroused when being french kissed?

Men may feel sexually aroused during French kissing due to the intimate nature of the act, which involves close physical contact and stimulation of sensitive areas like the lips and tongue. The exchange of saliva can also heighten arousal by triggering the release of hormones and neurotransmitters associated with attraction and desire. Additionally, the emotional connection and vulnerability involved in kissing can enhance feelings of intimacy and sexual excitement.
