Help!

I’m not sure if I’m in the right topic ... but I need help. Anyone is more than welcome to answer. My boyfriend told me recently we need to spice up our relationship. Which I totally agree , especially with our sex life . As a woman it has always been on my bucket list to have a 3sum with my boyfriend . I am totally comfortable with him and including a 3rd partner for a night . I need help on finding girls , and always some ideas on how to spice up the relationship ? I would really appreciate if you guys could help! Thank you
