Jeff was married to a woman but that ended a while ago. They had kids together and I think they're his main priority. There's a good interview with him on The Rialto Report website.
I don't think he personally even identified as even bi, but he'll never say his true preference to not alienate fans. He's very protective of his Jeff Stryker persona. You have to give him credit though, it was very enduring and very lucrative for him for quite some time.
I don't think he's ever discussed anything politics related, but I wouldn't be surprised if he didn't at least lean republican in some ways. He's a character for sure but doesn't seem to have the hatefulness in him like many modern-day republican's do.
