Sorry in advance if this is the wrong place for this post. I have been lurking for a bit and basically wanted to ask for some advice on a situation. Well to start I have been with the same lady now for 7 years, we are not married but I love her more than anything regardless. We have known each other and dated off and on since we were 12, but 7 years we have been serious.
Well about a year ago I went to another state to work and we had plans to move there after I got the feel for the job, area ect. Long story short while I was gone she cheated with another man. We eventually worked through it and are back together. Well now it has been about a year and our sex life is dwindling once again as it was prior to me leaving for the new job. I really do not understand as I make sure she is.... well "pleased" before we ever finish. She loves me tons and treats me better than I could ever ask, but somthing has to give with the love life.
I have been with nobody else since we have been together and I kinda felt jipped. I honestly care less if she sleeps with somone as long as I know in advance. I love her to death but fact is, if your love life is not up to par eventually someone will most likely do somthing...
Basically my question is am I wrong to think swinging might be a
way for us to liven things up. I know there are no perfect answers to this but opinions are all I am after.
