In a dorm, black lights would be okay. This is your APT, your bachelor pad, dont use the black lights. It seems like something stoners have in their room. The only time i would see black lights is at a party where every light is a black light whch is different from an apt.
Instead of the black lights, get candles. Lots of them. there is nothing better than having candles light up the room when you are making love to a girl/woman. Some scented ones wouldnt hurt to make the room smell better.
I have 2 of these on each side of my bed.

I got mine at ikea at 19.99 each. They look real tight with them right by bed side.
I also got some nice pink and red sheets for my bed. Nothing like the colors of love in your room. it really helps with the decor.
Have more than one pillow. The extra ones should be there for the girls that you bring home.
Most important, keep is clean, nice and smelling good.
