So me and my girlfriend have been together for 1 year and 7 months and i love her ohh soo very much!!! and we just started having sexual intercourse. But lately it seems like we have been falling back in lust. we miss each other more. we stay up talking late. we tell each other how much we wish were there to do things to them. so my point is, is it normal to fall back in lust with your partner? after a long time being with them?
