<human>: I've been thinking about this for a long time over the course of the past few years. I am 23 years old, she's 22 years old, and we've been dating for 4 years. I'm really happy with dating her and we get along extremely well. Sexually, I have a lot of interests that I've never gotten to look into because I've always been in a relationship. I just have the desire to have sex with other types of women - different nationalities, different appearances, different personalities, different sexual activities. I guess I'm just conflicted. On one hand, I care about my girlfriend a lot and I don't want to lose her. On the other hand, I'd like to try new things. I've considered suggesting that we have an open relationship and I'd be totally cool with that but I really don't think she'd be into it. Still, I'm not saying that I'm not up for asking her about it - I definitely would if the alternative were to just break up in order to fulfill my desires. I just don't want to end up staying in this relationship for the rest of my life if I'm going to regret it later. I understand that it really depends on the person, whether they'll regret it or not. I just don't want to end up 40 years old cheating on my wife because I was never able to fulfill my desires when I was the age and had the appropriate relationship status to do so.

/r/relationships, what do you guys think? Has anyone had a similar situation that could offer me some insight? Do you have an opinion on that matter to share? I've never talked to anybody about this, so I'd love to know how this looks from another perspective. Thank you all for your time.

Can you provide a brief overview of the text?
<bot>: I'm in a happy relationship with a girl who I don't want to lose, but I want to try new things with new people while I'm still young.
