I'm thinking of my current gf as a great candidate for a future wife (we're 23 and 24). She's really pretty, nice, smart, and her family loves me too.

However, she travels quite a bit since she's a mgt consultant at one of McKinsey, Bain, BCG. Maybe irrationally (?), I have this fear that some creep in upper management aged 45+ is fucking her. What can I do to eliminate (or at least alleviate) this fear? My brain says that this isn't happening, but I still can't help but wonder.....

Whenever she comes home for the weekend, we have a great fuck twice on the weekends and enjoy each other's company going to restaurants, parks, etc.

Why not just ask her, in more intimate moments maybe you could discuss this with her..

Yeah. Depends on her, but its almost certain to happen. Live with it. But she son't do it first or as often as you do.

But if you decide it will never happen to either of you, then it is almost certain that it won't.

Reality check - more than likely it is not her that is un-trustworthy.

It seems like you have trust issues and are shifting it on her. It's either your trust her or you don't. Make up your mind, make your choice and live with the consequences. Debating it non stop in your head is going to do nothing but end up manifesting is really sour ways in your relationship with her.

If you feel the the need to always know or have to ask just to relieve your fear - then you have trust issues.

I can speak from experience. For years as a younger man I felt threatened by any man around 'my woman' who I perceived to be superior to me in some way .. better job, better salary, better car, better looking, better etc .. Only to be clawing my brain out when 'my woman' was not around wondering where she was, what she was doing, who she was doing it with and secretly suspicious of all her 'friends' and 'coworkers'.

It all came down to my inferior view of myself. Once I grew up some more and grew some confidence in myself - my trust issues with women and people in general evaporated.

My last relationship was with a woman that had a very close working relationship with some upper management males. Never once did trust become an issue - because I knew I could trust her. Our intimate romantic relationship did eventually end, but it was because our lives (personally and professionally) took us in different directions and we still remain good friends.

I've been shit on twice in relationships. I don't trust anyone any more.

Don't focus on the behavior, focus on the motivation for the behavior.

I had a GF who fucked other guys. She didn't "love" them, she just loved the thrill of it. I was fine with her getting some strange on the side. We had an agreement. She could fuck anyone she wanted provided she didn't hide it from me and if she developed feelings for one of them she either cut it off or told me straight up and didn't play me for a fool.

She was so turned on that I was supporting her it became a fun game. She would fuck a guy, then come to my place and tell me in graphic detail what they did, how many times she came, and all the while I'd be licking her fresh fucked pussy or fucking her. It was great!

I am a firm believer that people should not be treated like property. If my wife wants a strange cock she has my support to go get it. I'm far less concerned with the action than I am the motivation. If my wife were to fall in love with another man and hide it from me that would be hurtful. If she came home with a pussy full of cum because she fucked a hung stud and enjoyed it, that's fine.

This is an excellent point. People cheat because the side relationship is giving them something they desire that their regular relationship does not. Could be sexual, could be emotional, or some other reason. We all have needs, and if our relationship doesn't meet one (or more) of our important needs, then we can be tempted to seek out those needs elsewhere. And contrary to popular belief, the reason people cheat are often not because sex is lacking somehow-- the sex with someone else is just and expression of what other qualities draw them to that person.

So to the OP, I'd ask, what is it you fear your partner might be tempted to seek elsewhere? Think about what needs are most important to your gf, and talk to her about she values most from a partner. Men and women often prioritize needs much differently. You might be surprised what she values most from you. And you might gain some confidence that what your relationship brings her means you have no reason at all to worry she'd be tempted by others.

And it is also worth mentioning that even if a person has the desire/temptation to cheat, and the opportunity to do it, doesn't necessarily mean they will go through with it. Some people feel a loyalty to their partner that outweighs temptation.

If you don't talk about relationship boundaries, how serious you both feel, if you are both monogamous, etc...you will never know. You can't just think that someone is cheating because they have the opportunity. You have to know what she thinks, and if she would consider it cheating or not.

My wife and I have a simple rule. Look but don't touch. We are both human and appreciate looking at other people. We both know each other will find other people attractive. We both know each other masturbates (obviously if I'm on this site haha). But we don't touch anyone else. We are apart lots of times. We both have opportunities. And we don't cheat. I don't worry about it at all. If you don't understand each other's views on it, you won't know what is considered okay for each other.

If you girlfriend wants a monogamous relationship, then she is probably not cheating. You need to know what she feels like and then trust her. If you can't trust the one you are with...then IMO, you shouldn't be with them. (And it might not be their fault either as some people have trust issues)
