Asking new partner(s) to get tested ?

I’ve been married for the last 5 years, now that I’m divorced I’m wondering how I go about engaging in sexual intercourse with new people...safety from STDs is my primary concern as I’m wanting to “sew my wild oats” as they say. Threesomes, one night stands. I’m willing to show my STD testing results but how do I request new partners to do the same without sounding paranoid ?
