The kiss is very important... the way they kiss is very important. and when they are leaving, if they look back one more time before they're gone... that's important.
Between two masculine gay/bi men, deep kissing (along with hugging and caressing) indeed goes a long way towards "setting the stage" for the "main event" to come. From what I have read (I have no personal experiences to share, being celibate for 65 years) the kissing further and deeper cements the bond between two males having sexual relations with each other. Personally, I view it (m/m "tonsil hockey") to be HIGHLY erotic and VERY stimulating.......
I'm with the kiss army here. Sorry for the bi intrusion, but when the juices of love are involved, I wanna take part. Passion holds sway and I want your tongue.
It wouldn't be a deal breaker at all. What I don't like are teasers. As long as they are honest I am game.
It doesn't matter to me if the guy doesn't want to kiss or if he does want to. I am open to either and have found that either way my legs end up lifted and spread wide and his cock buried in me.
To me, kissing is something that I don't want. Although if it's in the context of rough play then that's all part of it and should be done with force.
