My wife and I have been together for 18 years. We love sex, and have it approx. 2-3 times a week. I'd like 3 or more times weekly, but that's a diff. story. There are times when we have sex 3-5 times. My wife is pretty hot, 5'5" Double D's, small waste, nice firm ass, long hair, nose ring, very tan, approx. 180lbs. (Yeah i know what you're thinking...180 @ 5.5)??? She use to body build, and still works out 5 days a week. 3 kids later, getting back in shape. Everyone that sees her, thinks she can't weigh more then 140lbs. (Everyone knows Muscle weighs more then fat). she doesn't look like a yoked man, but firm, and thick muscle legs. Anyway, when we have sex she really appears to enjoy sex with me, and have told me many many times that i am pretty great sexually. I don't think I'm bad, but i do have an issue with my penis size. I'm a little longer then 7" (barely), and approx. 5.5" thick. When we fuck, she Ogs. multiple times, and does the hold verbal reinforcement thing pretty loudly. We had a pretty serious talk about faking Ogs, and feeling better then it really is at the beginning of our relationship. i told her that if she faked it, i would think i'm doing a good job, and never get better...she would continue to suffer. Don't get me wrong 1 out of every 7-8 times we fuck, she does tell me "No, i didn't cum, but it felt great though." So it appears that she's keeping our agreement. I'm pretty sure she doesn't fake with me, as a matter of fact she talks about how ridiculous it sounds when people fake sex (e.g. Porn). She contently tells me that I'm a very good size for her, and really isn't interested in a bigger dick, because she couldn't imagine it being too much better. Although she's told me that, I'm not stupid, i know there's 1000s of guys out there better then me. She too has admitted that yeah, that's probably true, but insists she is very very satisfied. She's only had one other guy in her life (First BF) approx 4times. and insists it wasn't even close to us now. I love sex, and do know that i satisfy her pretty well, but i can't shake this feeling that if i were bigger, she would just scream with pleasure. A couple of times we experimented with objects in the house. During those times she really seemed to be able to take much more, and also enjoyed it very much. About 9 months ago i fingered her, and got more agressive...i got four finger in (i have big hands) she got wetter then i've ever felt her get, and came as loud or louder then with my dick every before. Obviously as much as she love my dick (according to her repeatedly) I have to be right that she would want and enjoy a bigger dick then mind RIGHT??? We have and awesome relationship in every way. Because i love everything to do with sex, and we talk about everything very openly, i asked her "the question?" Out of all my friends, who would you want to fuck if it were okay with me? Of course she acted like she really had to think hard, but we know better right??? She finally came up with three guys names...I was cool with knowing. Of course i would kid her about it for the next couple a years referring to the guys as # 1, # 2, and # 3 in the order she said she would want to fuck them. Also for years she has known, that I've always had a fantasy of seeing her fuck another guy (With a bigger dick)About 8 months ago a asked her seriously about fucking # 1, which we had and 1000 question dialog for weeks where I asked every question i could think of, and then some, and she was as honest as she always is with me. ExampleI asked things like if his dick is bigger, and you like it better will you tell me so? She very clearly said "Yes, but that won't mean that i won't want to fuck and still enjoy you after." I asked her if he fucks her better the me, will she tell me so? Same reply) Everything a couple about to do something like this could discus we did. I know this whole thing comes from me not thinking my dick is big enough. Even though deep down, i know it's not small (when erect), but i wish it were bigger. I would love my dick to be at least 8" solid, and if i am 5.5" around now, i would want to be at least 7" around. When i stick my dick inside her, i want to se the reaction of OMG. like the porn guys. I see all the other reactions during sex like those guys, but it would be nice to pull out a dick that would make her say Damn! or Fuck! She hasn't fucked this guy yet, but we both have agreed to make it happen by the end of the year. I know many relationships break up after something like this, but we both are pretty sure this won't happen with us. My wife says she really doesn't care if she gets to fuck this guy are not. She has admitted that yeah it would be cool to experience someone else, because she's only had BF # 1 in High school, and me, but she says if it happens, great, if not who cares. she's pretty admit about that, and never brings it up, and i think a little tired of me talking about it. If anyone is interested in something like this, i have a fucking awesome Survey I typed up for after she fucks this guy. All the questions anyone could want to know after his wife fucks someone else. So all that being said, i have two questions: 1) Is it okay that i let my wife fuck another man, if we're sure it won't affect our relationship, and really are only interested in it being a one time thing? 2) Am i right in thinking my dick is pretty small compared to what she could take and would rather have? Yeah she loves my dick, but come-on if she had a huge fucking dick in her, she would fucking love it. She's taken Shampoo bottles before.
