Well first off congrats (although I have to admit, I do not know what a BAC is hehe) but I can say going back for schooling is always a tough step (I know as I am doing it myself hehe, 39 more credits to go *groan*), keep up the perseverance and dedication!
As for help on how to set up a threesome, there are a few personal websites you could try...but honestly I think they are a load of crap (Jenna if you read this don't be discouraged, just my experience, your mileage I am sure will be different), but if you are interested, you can take a look at Adult Friendfinder (
www.adultfriendfinder.com). My experience was horrible there, but you may get some actual sincere responses as a couple than a single male, so, take a look and if it seems something good to you, then by all means sign up and post.
Then there is the other option which is "sleazy" but if you are both comfortable with it, then by all means, why not do it, and this is...hire an escort. While it may not be the optimal choice, it is another option for you. I am sure if you did some research you could find a reputable service or escort in that area. Anyway, good luck to you in your search!
