My girlfriend and I have been dating for seven months. She asked me out and it threw me for a loop. The first few months were amazing until recently when the "honeymoon" phase of a new relationship ends and reality sets in. We've had fun, going out on dates and spending time together nearly every weekend. I felt absolutely ecstatic to see her and go out with her. I never thought of wanting sex with her, I just loved passionately kissing her and it felt amazing.
I tend to spend the night at her place when we go out, sleeping next to her in clothes, and she was always comfortable with me touching her breasts over her clothes when we started going out after two months. Touching over the clothes felt great, but then I wanted to feel more...under the clothes. She and I recently we admitted that we really wanted to have sex with each other. We want to wait until marriage, so we settled for humping. She wanted me for six weeks and me probably a bit longer.
I did some humping with my girlfriend for the first time and it felt amazing afterwards; like it all felt right. The second time we did it, it was great too, but afterwords, I felt empty, and unfulfilled like crap; like something didn't feel right; it felt meaningless. Undesired, repressed thoughts came up that I had just used her, that I only wanted her for sex, that I didn't love her as much as she loved me, and that I wanted to immediately leave and create some alone time because I didn't feel any connection after we did humping for the second time; I got really worried that I didn't love her enough, or that she was too young for me because she doesn't have independence or good social skills like I do. (I'm 29 and she is 19.) I even felt scared of staying committed to her.
But she went through with it and wanted it, she said she felt an emotional connection the second time, but I felt nothing that time. I'm relooking at the situation and wanting to do more things that show love instead of lusting after her.
Is this normal to feel empty and unfilled at times? Do I have a problem with loving my girlfriend? Am I just addicted to sex and lust? Are these just symptoms of anxiety? Am I always supposed to feel butterflies towards my girlfriend?
Or is it just science at work with dopamine levels decreasing?
