In Fable 3 for the Xbox 360, you can have sex with various townspeople all over Albion. There are a couple different ways to do this.
1. You can propose to and marry someone of the opposite sex. You’ll need the Family and Lover packs for this one, because you’ll need to be able to purchase a house, and you’ll need the expressions necessary to propose marriage. You’ll also need to purchase a wedding ring from a shop. Once you’re married, take your spouse by the hand and lead them to your house with a bed, and click on your bed to sleep. You’ll see the protected or unprotected option.
2. Anyone that is marked as Flirty will have sex outside of wedlock, without much of an effort. Start a conversation with someone, and hold RT to show the information for that villager. It will say something like “Common, Straight, Flirty” or something to that effect. If they’re Flirty, then use enough expressions on them to allow you to hold their hand. Lead them to a house of yours with a bed, and click on your bed to sleep. You’ll see the protected or unprotected option.
3. There are whores in some of the lower quality areas of towns. They’ll be fairly noticeable on sight, and they’ll have a name with “the whore” in it. Once you communicate with them, you should have an option of “sex invite” by hitting RB. They’ll start following you immediately, without having to hold their hand. Lead them to a house of yours with a bed, and click on your bed to sleep. You’ll see an option for protected or unprotected if you have any condoms. You’ll probably want to use a condom so that you don’t risk getting an STD.
