  • I guess there's an evolutionary advantage to exchanging saliva with others, you pick up small amounts of bacteria, most of them are friendly ones, but some aren't.

    Personally I think kissing is gross, especially with tongues!

    I’ll take my chances and avoid. 

    Kissing is meant to release love hormones such as oxytocin and dopamine, yet kissing would likely cause my body to release cortisol. Body contact is sometimes acceptable, but only if the person is a very good friend. I’d much rather cuddle up to my dogs.
