I'm going into my third year of a great relationship, and there's a growing possibility that this might become a lifelong endeavor. Lately, I've been thinking about this a lot, surely making a bigger deal out of it than it should be. Before me, my girlfriend had one sexual partner, and a few oral sex partners. Before her, I once fingered a girl (and did an awful job at it) through her pants. In other words, I never even saw a vagina. So, as the days keep going past, I am thinking more and more "Wow, I might only have sex with one person my whole life" and "I wonder if it's smart to have sex with more people to be sure I am ready for this commitment". Of course, I can't just say "hey honey, I want to have sex with someone else just to see what I'm missing if that's cool..." These are transient thoughts, and I don't take them too seriously. However, I'd like to know what you guys think. How would you feel if you knew you would be with one partner your whole life? Would you want to try sex with other people? If so, do you think it's important, or just a fleeing desire? At times, I know it doesn't matter one bit. At other times, I am so resentful of my sexual past compared to hers, and I realize she is relatively innocent in the scheme of things. Is anyone else bothered by a similar situation?
