emotions

So last night I felt emotions I haven't felt before in my 3 years of marriage as my husband and I were being intimate. As he was massaging me down there I just felt the urge that I really wanted him in me. I have been on birth control for several years because of endometriosis. I stopped taking them almost a year ago, and we have been using other forms of protection until we decided to star ttc. Could the strong emotions be due to finally getting "back to normal" after being off the birth control?
