Don't know if you have moved forward on this but from someone who has been in your shoes before don't do it unless you are 100 % ok with being involved and you have the utmost trust in your relationship. It can and will tear you and your relationship apart! It opens doors that if you do not communicate on every aspect and talk about things very clearly you will get hurt. Please trust me on this. It is not worth YOUR mental anguish. Read, read, and read some more on the lifestyle. I wish you better luck than I did and my relationship was one of 9 years with alot of trust but lacked communication. It can ruin you if you are both not into to it 100%
