Love is about giving your heart away... or even kidneys!! lololol.
But on general terms... love = marriage + babies. Tee-hee.
X = Y - Z
X = love, Y = Sex, Z = no babies
so technically love = sex - babies
i just think when babies arrive, sex and love between couple go down. all the guy giving more love to wife after babies is all bullsh*t in my opinion ...sorry ... anyway just for fun & kidding, dont take me too seriously
