I think you might want to give a little more information?
So. For example. Do you drive? Would you be able to get across to New Orleans for example? Check out some bars?
Or do you want/need to do it just via internet? Thing is, LPSG isn't strictly a dating site, though it does have some facilities to help with that. If it's just internet/email etc., how are you going to create the mutual "trust" that is generally essential for such things?
Also, you need to mention things like what kind of experiences you
have had, and what you seek. For example, do you want to fuck someone, or do you see yourself experimenting as being the receptive partner? Some people will be wary about first timers, and would prefer you to have done something already ( say, blow jobs or hand jobs with other men ) and others would be cool with it, and look after you properly.
I would
like to think you'd also be able to specify some "context" for it. For example, are you gay/bi? Are you in a relationship with someone else? Do you want this anal sex experience to be a standalone thing, just to satisfy some curiosity / lust, or might it be part of an ongoing friendship, or romantic relationship?
Just my thoughts. I hope they help. I am about 4750 miles away from you, so I can't really help directly, but I thought you might find some "theory" useful ...
