Girlfriend is a nympho!! help me

Okay me and my girlfriend have been together for about 5 months now, and have had sex almost every day. recently i caught her on craigslist trying to find couples or girls to hook up with, and i asked her why... she says we have sex alot and its not that its not satisfying... its that its the same over and over. she wants to change it up a little. okay well weve tried every position and done everything and i dont know what else to do.. im scared that when im out of town or staying at a friends shes going to have someone over.. what can i do to prevent this?? or what are some new things i can do that will blow her mind?!? advice is very much appreciated!!!

why don't yall try having a threesome with another girl?

i was going to! until i caught her trying to have a 3 some behind my back. she doesnt want me having sex with another girl, and i dont want to watch her screw another guy. I always think she wants to screw other people. But our sex isnt all that bad... i just think weve had sex so much, shes ready for the next dick. i want to spice things up and all that but its not easy for me.

so what if you just didnt fuck the other girl? fuck her while she plays with her....?

sounds like more of a trust issue.

its only just now become a trust issue, because of her going behind my back. she has no problem trusting me, and i dont give her reason not to trust me. but i like your idea... i dont know how well that would work... .if the other girl wanted me to fuck or play with her my g/f would get angry, or maybe say yeah whatever, but be mad afterwards.

i dont really think that needs to be an issue. you make it clear beforehand that there wont be any fucking between you two or maybe your gf will be ok with anything but penetration.

okay cool. we talk alot about our sex life and what not. so ill give a chat to her today when she gets home. anything i could do when its just me and her to spice it up a bit?

Not sure if your thinking long term relationship, having fun while going to school or maybe you just don't know.
If its all fun and games then have at it.. Mix it up, be safe and enjoy..... however, if you even remotely fancy the notion of this girl being the * one* then this is red flag city and I'd say off cuff, get the F* out of there. Can you seriously see this relationship running 40+ years ?

im not sure what yall have or havent done. yall could add toys, different oufits/costumes, try blindfolds or handcuffs or tie each other up, different locations, etc

i could!!! the only problem is the sex..!! its an EVERYDAY thing maybe 1 or twice a day, and she wants it to be that way forever. she thinks its every guys dream.. but really its not.. i dont enjoy it as much anymore.. because like she says, its the same. i want to wait a week at a time but it never lasts .

then you also need to tell her that! she thinks shes making you happy when shes really not, just be honest with her

ill pick up some toys/outfits this weekend. she used a nurse outfit once and i loved it. we'll probably have sex when she gets home in an hour. Its almost as if its expected from me. but you see.... i give and give and give. pleasure pleasure pleasure.. which i love... but not when i never get anything back, ever.

Reading your first posts: She wants to play around behind your back, tried a few times, maybe succeded, yet you are on her terms to have only her, maybe more in a 3some?
It maybe harsh to suggest to let her go. Trust issue, you cannot trust her, her terms. A relationship is not a one way street.

exactly. for example today. i got a call to work tomorrow which means i stay in coppell tonight and come back friday night. All i could think about was her having someone over while im gone.

When you say "caught her trying to have a threesome" do you mean she was trying to get hooked up with some other guy and girl?

It's clear there are trust issues here, and that can very much be a deal breaker. If she's got no control over her libido and she's willing to go behind your back to have sex with others to seek that next thrill, but then says you can't do anything with anyone else, IMO that is horseshit, and she needs to be called on it. She absolutely has no business going behind your back for one, and the double standard is just a whole other level of what the fuck.

Seems to me there are 2 options here: you talk to her and make it clear under no uncertain terms that what she has done is unacceptable, as are her double standards, or, you break up and leave it at that.
