Steve If you feel it it will be fine with her than why not but I recommend you talk about every detail in advance.
- What does she understand taking the lead? In some parts or all of your relationship?
- Under what conditions will you be open-minded and when and how often will you have sex?
- If you can not fulfil her expectation will their any penalty?
- What influence and in what way are your wishes taken into account?
- If you decide you don't want to continue the relationship, will she hand you the keys straight away?
- How should the finances be regulated?
If you live in a flat, who will be in the tenancy agreement?
etc.
