so sad, these people not engaging in kissing. maybe practice light nuzzling. pecking, gently pressing lips together, touching tips of tongues, bumping noses. then move on to stroking and kissing fingers. you don't have suck each others faces off for it to be lovely and sensual.

if you feel shy with your partner, why not just say, "I miss kissing" to break the ice. if you don't feel shy, back him or her into a corner and take the kiss. then tell him or her, "I miss just kissing you."

it should give your partner a lovely shiver to be so desired.
