I’ve had struggles similar to this with my past partners as well. I think it’s a good idea to have open and detailed conversations with your partner about boundaries and even about things you may be curious about/want to try. Create a safe and open space between you and your partner, try news things and see if you like them. If you don’t, no big deal.
At the end of the day it’s all in what you and your partner are comfortable with and enjoy doing.
Hope this helps a bit.
