I had a similiar issue when I was dating my wife who was rather tall (almost 4 inches taller than me). We fixed the issue. When I walked her home I would spring up the stairs to her home, one or two steps, Turn around and kiss her. We managed to always find a way.
What's wrong with stretching?
I'm 4'11 and my husbands 5'10. I always find a curb or just smother him with kisses when he's sitting down.
When there's a will there's a way!
Hmmm....some sexy high heels (?)
Back in the day I dayed someone a foot taller than me. Steps and curbs were me friends.
I never minded standing on my toes. Sometimes my tall husband used to lift me up to kiss me. On occasion, I would reach up and pull him down to meet me. Kissing was never a problem for us.
When you are trying to kiss, you don't think of other things. If you do you're not completely there?
