Mid life crisis?

My S/O, let’s call him K and I have been together for over 8 yrs.

We met in a very conservative church and have evolved together and no longer go to church. But still identify loosely as Christian. Him more so.

I recently came out to him as bi. It’s something I realised very early in our relationship but the church homophobia had me closeted.

We are in a very happy relationship but I think because I was raised religious and im finally out, I regret not having explored at all. I waited til marriage so he is the only partner ive ever had.

Now I’m at a loss because I feel like all my suppressed lust has kicked into gear, I feel like I’m 20 again. I feel hot, Im feeling myself, dressing sexier. I want people to find me attractive and I wanna fuck around, which is pretty scary.

I’m not looking to lose the person I love most in the world but I also know stuff like 3somes or me trying out with other folks is basically off the table for us.

He is very insecure because he doesn’t feel good looking so me bringing up any of this he would take it to heart and think I don’t want him anymore. He is also very very vanilla and I accept that that is who he is.

Is there a safe way I can deal with all my raging hormones without potentially destroying my relationship? Or should I just take a cold shower.
