Why do his lips tremble when we make out?

[yourwinglady]

Today I looked up at him after kissing and his bottom lip was trembling a little bit. Why does this happen?

[markscott]

If it wasn't cold out, then he was most likely nervous. Or it might have been a little tic. If you are in a relatively new relationship, it's common for the guy to be nervous. If you have been in a relationship for a while with him, he may have quivered his lip due to the emotion while kissing you.

[SirRexington]

He is so taken back by your kissing skills and the passion he has for you.

Probably nervous
