Not to get too detailed but the tongue to tongue action is a kind of simulation of what you might do with your tongue shortly after kissing, which makes it a kind of preview. For me, anyway!
A little bit of tip of tongue touching is genuinely nice. Full on "here's all my tongue" kissing generally isn't, should probably only be used to _briefly_ punctuate some related action or feeling.
The same happens to me. The tongue doesn’t do anything at all for me. All of my girlfriends seemed to like it though. This is contrary to what the article says, but I understand that every person is a world… which is why looking at kissing scientifically makes little sense to me. Just try things and see what works for both of you (and don’t neglect doing things that don’t work for you if they seem to work for the other person, of course)
But seriously. Don't you get aroused when you get the woman into a aroused state? I definitely get. There is nothing more satisfying when you can make the woman want for more. The game of teasing. You play, you stop. She wants more and more till it's unstoppable.
each person is different. there's people who don't like kissing so much, or like it with no tongue best.
it's all part of the game: mutual communication about pleasure
