if you are 100% sure you want to go through with this, & you say she has in the past, expressed interest in having another guy, then your remidy is simple. you should first find out the exact type guy she would be interested in sleeping with (IF she were to do it). then YOU & you only have to do all the leg work when it comes to finding that perfect guy. when your sure you,ve found the right one, set it up for him to come to your house ( thats probably the only place she will feel safe) while she is gone out. work out all the things you need to for your situation, like where he will be, where you will be, & where you want it to happen, before she gets home. then when she gets there, do all the things you would do to make her hot & ready for sex (with him waiting in another room of course). making sure you hit all of her hot spots & getting her super turned on. then start mentioning some of the things she seemed to be interested in before. get her comfortable talking about another guy. then start asking her if she would do that for you, if the set up was right. once you get her to admit she likes some of the ideas, ask her if she would REALLY be interested in it ( being carefull to not let her forget for a second that this is YOUR idea & its what YOU really want to see, never, ever put it on her). if you have her in that situation, & she admits she would enjoy it, tell her you have another guy in the other room fight now, & you really want to see her with him. if she is at all interested, she will at least allow the other guy to come in. now, here is the key, you have to be sure you've picked the right guy for her, & you have to talk with him some before hand to let him know what he needs to do, how he needs to present himself when he first walks into that room (this meens EVERYTHING to a woman). if she sets eyes on him for the first time & likes what she see's, coupled with the fact that you brought him there to have sex with her, & your actually lying there on the bed beside her. she will follow through. maybe not actually having intercourse with him. but some form of intimate activity should happen. as for my situation, i was once in the same boat as you. i worked it out just like that & it went fine. once she realized i was serious, & then saw the guy ( he walked in completely nude, with a huge, raging hard on). it was just a matter of time. she has since told me that she never knew anything could make her feel so erotic. we laugh now at things she used to say she hated & wouldnt do, & how now most of those things are her absolute favorites. well, i hope this helps you in your decision, please right me back & tell me what happens, ttyl
