YOUR QUESTIONS: I've been with my boyfriend for 5 years, and he's suggested introducing 'others' into our sex life for the first time. Which could be hot. Do you think that ending the monogamous nature of our relationship would put out loving stable relationship at risk?

It can be risky, it can be very beneficial. It needs to be something you both do with the same level of agreement and comfort. You need to constantly communicate with each other about your thoughts and feelings and if ever one of you is not comfortable with something you must say straight away. It can potentially a whole new level of excitement to your sex life and possibly improve your relationship even further.
