So heres the issue. By no means is this a way for me to boast, I am just expressing how I am feeling and my legitimate concerns. I would say that I am a handsome man. I started getting a lot of attention from girls in high school, but mostly because of family issues (my parents were stressed with the foreclosure of our house, their health problems...etc) I never pursued any of these girls beyond just a friend because I didn't want to add that potential extra dimension to our family problems. It's not that I never had interest in girls, I just figured that I would be able to fully capitalize on relationships in college like a normal teenager, when my parents wouldn't have to worry about me partying, drinking etc...
And it just so turns out that I end up going to a fairly conservative catholic school where (most) people did not "party" and hookups weren't common at all. Most girls were pretty conservative. But regardless, I started dating an incredibly wonderful and beautiful girl my junior year. Needless to say, she was more experienced than I was (only by the virtue of her having had 3 boyfriends in her past; she was a virgin when we met). We instantly formed bonds and eventually lost our virginity together after our first year together. We are still together (2 years now) and I plan on marrying her after I am financially secure.
Here is where the problem lies. I am currently in graduate school and she is working in NYC. My classmates and people I've met at bars/clubs have tried to pursue me but I have been steadfast in my resolve to never cheat on my girlfriend. At my worst (horniest), I have had awful thoughts of sleeping with other women, but those are easy to quench with masturbation. My problem is that I know and am confident that women find me attractive and as a guy of course I will find other women attractive. My question is; should I have more experience before I decide to marry a person?
In addition, we live in a culture where random hook-ups are acceptable and the norm and men are expected to have 7+ partners. I kind of feel like I'm missing out by having only been with 1 person. I know the argument; that I am lucky to have found a wonderful person who has given herself to me and 98% of the time I feel that way as well. It is just this other 2% that i am DEATHLY afraid of.
Any advice from women?
Or guys who have been through this?
