I’m reaching out for some advice and support

How do you have that tough conversation with your partner about feeling unhappy with your sex life? For example in the past 137 days we have only had sex 2 times…..

I want to communicate my feelings without causing any hurt, but I also need things to change. Any tips or experiences you could share? Grateful for your support! We have been together for 5 years and our getting married this year

P.S. Every time we do have sex we always say “we need to do this more often” but we never do anymore at one point and time it was great. 😔
