You may want to try the online route. I'd suggest Squirt or Scruff. There are a surprising number of people in your position who are on those sites looking for similar things.
But, some words of advice:
When you make your profile, you will get a lot of attention because you are new. Most of those will be from regulars to those sites. I would suggest being particular with who you engage with. Read their profiles. Try and get a feel of them, to see if they are serial cruisers, or genuine people like yourself. Talk with them. Open up a conversation, and chat away. People who want to treat you as a notch in their belt will be fairly transparent, and want to hook up right away. Someone like yourself will want to get to know you as well, to develop trust, and feel you out as well.
Be honest in your profile about what you are looking for. Discretion, safety, clean, and whatever you are willing to do, as well as what you are looking for in someone else. If you get to the point where you want to meet up, where would you prefer that to happen? For example, your place, his, in a car (yes that's a thing), or elsewhere? Things to think about.
Pics. Some people will push you for nudes and a face pic. Be aware that some people are online to collect those, and don't really have any interest in meeting you. So. Be cautious. I'd suggest developing a level of trust with someone first. Have a couple of conversations, or more, then exchange pics if you want. OR, arrange to meet in person for a hello. It doesn't have to be coffee, or a beer, but someplace public or private where you can say Hi. I'd suggest someplace public where you wouldn't normally go, so that you won't bump into anyone you may know.
Of course, if going online isn't your thing, there is the other route of meeting someone the traditional way. Like at a gym. While that would take longer, you would also have the benefit of developing some sort of friendship beforehand, and all the above information wouldn't apply. It would be very organic, happening as your friendship develops. But, you'd also have to be willing to step outside of your shell a bit to make that move, and be aware enough to know the potential is there with that person.
Things to think about. Good luck!
