First, get that job, because even if you're just looking to get laid it's going to take money some way or another. Then if sex is all you want, then I agree with MmeIntentional, just hire a high class prostitute. I'm sure a higher end "lady of the night" will be willing to come over to your place seeing as you have no car.
Sorry if that's crude but I want to say it every time I see a guy post here that all he wants right now in life to have sex for the 1st time.
