Technically yes. In Megaton, in Moriarty's Saloon, there is a prostitute who will 'go to bed with you' for 160 caps.
It's 120 caps; learn to count.
If you sleep in the big bed at the top of the stairs afterwards, she will be lying in the bed next to you. Talking to her will give you her normal dialogue options. Yes and no because it will do nothing, no noise ,nothing, but with mods it will show what it looks like..
