My advice after being with my lady friend for nearly 6 years.
If your not seeing her a lot, try to see her more.
If your seeing her loads, try to see her a little less.
It seems so obvious but it works.
Little surprises seem to work well, nothing huge but small things, i feel so soft, but kissing their neck when they're walking in front of you etc works well for me.
Now i go sit in the sissy corner of shame.
