Do I need to tell current partner that I used to sleep with one of my now friends?

I’ve been with my partner for 8 months now and it’s been playing on my mind a bit that we haven’t ever really spoken about past relationships. I’m aware he’s had a few and he’s aware of mine but we’ve never discussed people or anything.

The reason it’s been on my mind is because about 6 months before getting together, my best friend of around 5 years and I slept together a few times. I don’t have any feelings there and didn’t at time time, we had just flirted on and off a bit for a long while and it ended up happening. We are still really good friends now, and will sometimes hang out alone, but it would never happen again and I am incredibly happy in my relationship so would never jeopardise it.

However, is this something I need to bring up to current partner?
