An alter ego will spice up your sex life. Have any of you ever tried acting wile making love or creating an alter ego? I must say it has been one of the best things we have ever done to spice it up. Lets say you are a clam down to earth person you can try being the dominator in the bedroom it can give you such a rush and we all know the more the blood is pumping the better everything feels and who knows your s/o my just like it ( mine does ).
Another example to take it even further is by you both creating alter egos and go out lets say to a bar or night club as the egos and pick each other up as your alter egos. Lets say her as a nurse in scrubs relieving the stress of the day with a good hard drink ( you could wear a something sexy under the cloths) and him a sexy delivery man. Have fun with it and don't make it easy make him buy you a drink , dance a few dances, then make your way home or to a nice hotel and have him deliver his package.
There are so many different things and alter egos you can use. No matter how long you are together you should never get bored with your sex life don't let yourself get into a routine. Have fun talk about what you want from each other, you may just find out new things about one another.
