just be open and ask outright about it in a nonthreatening non accuastional way... if a couple cant talk about something so important, they are in deep poop already
you will never miss, give some time..do not over expect the biology..
Have you ever watched "Hall Pass" movie?
well, in my opinion just try to look for why do you feel such a feeling like that, i bet that there must be something that makes you feel that....
I've been dating with the same guy for about three years till now and i still fine with him..
I was in this exact same situation about 6 months ago. Physical intimacy can largely affect your mental and emotional intimacy also. Sex is a way to build that intimacy with your partner. When the sex slowly started to decline, we slowly started to lose intimacy in other areas too. It came to the point that even after directly and telling him several times that these were issues that we needed to address, I had to end it. I didn't feel connected to him anymore in anyway.
You know, opinions and feelings on monogamy are quite vast. I know of people who feel that if two people are attending to each's needs in a relationship and the relationship has everything necessary to keep the relationship great done, then exploring with other people with your partner can be quite an enhancing experience you can share with each other.
I don't know how I feel about that, isn't swinging something like that? Either way, I hope you well :)
Be honest with him, tell him exactly what u r Thinking, I'm sure that will work
Get him a Kama Sutra book ;)
See if he has any fantasies he wants to explore, and try it. Adventure could be a great way to liven things up.
Tell him directly but be careful with how you say it,
So think it through very thoroughly if you must but it is better you let him know instead of keep it bottled up, I'd kill for a woman who would love me enough to tell me anything she wants or anything thats bothering her, he may even appreciate you telling him.
