Fable II

Fastest Method:
Travel to Westcliff and just to the right of the crucible, there's an inn. Just outside the furthest door to the right, there's a prostitute. Marry her, and then come back to the room she was outside of and go in. There are 4 beds, so since she never rejects you, just rotate through the beds using the 'Come To My Place' expression. Should take around 5-10 minutes overall.

To get this achievement, you must Make love 25 times.

The best way to do this is find your wife/husband, and use the "Come Back To My Place" expression on them, and go to your home, and to your bed.

Protected or nonprotected, whichever floats your boat.

Then, afterwards, sleep for 7 days. After which, your wife will be where she was before you went to sleep. Use the "Come Back To My Place" expression on her again, take her to bed, choose protected or unprotected, and repeat until the achievement pops up.

It's only Marital and Extamarital sex that counts in this achievement. So any Paid For Sex will not help you here.

I found that the Come Back to My Place expression works better on ppl with a white heart or just close to a white heart. The red hearts want to get married and will refuse on that premise.

Make love 25 times to get this achievement.

Remember that you need the DLC called "Fable II: See the future" to get this achievement. It won't work if you don't have it. I don't know if the free version of this DLC works, thought. But I know you need the Premium version of the DLC.
You can try and download the free verion of See of future to see if it works.

You need the "Come back to my place" taunt, which is sold at the bookstore in Bowerstone. The book is called "Come Hither, Dear".

You have to make love to your spouse or to someone you know well. Times paid for sex will not work! Only times had marital sex, and times had extramarital sex will work. As long as you don't pay for sex. Sex with a whore will know work untill you mary her. If you mary a whore, you will be able to make love to her as much as you want, she will always say yes. Sometimes she refuses, you have to use "Come back to my place" then "Follow" taunt. She will always obey. Another spouse (ex; villager) will not always agree with you, but only once a day or week.

Something like this should work;
Times Had Marital Sex - 13
Times Had Extramarital Sex - 12
Times Paid For Sex - 173

Also, protected or unprotected sex doesn't matter. You will find some condoms to any general stores or cloth stores.

I found the easiest way to do this was to marry a prostitute. I married the one from westcliff (standing near the side door to the inn) and took her back to my home using the 'come back to my place' expression and went to bed. Once they are finished, just use the expression on her again and get back into bed. She will never refuse you so it is much faster than having to wait or sleep between each time with another partner or villager.

Just make sure you have collected enough condoms first (if you want to use them)

For this one you need to have sex 25 times. Easiest way of doing it is to marry a prostitute in Bloodstone, and constantly have sex with her. With or without a condom won't matter.

Or you could use the guide below.

I've helped 100+ unique players with achievements in Fable II and I have no intention in stopping. Players join my game, and I will unlock the achievement within a very short period of time after you've joined. The procedure is swift and requires nothing from you except that you have both of the DLCs installed. This can be either the free versions or the premium ones.

As long as this achievement is up, I'm offering the help. Simply send me a friend request, and a message stating the reason you've added me, and I'll help you the next time I'm free. Please don't send me messages asking me when you can get help, as I always keep in mind my "businesses" and I won't forget about you. And because my friends list is set to only have certain people, I can therefore not keep you on my friends list, unless we've agreed that I will.

Now, go ahead and send me those messages! I'm eager to help out :)
