Visiting a man at his home or inviting him to your home does not automatically mean that sex will be involved. How do you know if it is safe to venture into this realm? It depends on what your intentions are. If you have established a rapport with your date and you know definitively that you do not want intimacy then it is probably best to get that out in the open prior to finding yourself in that situation. If you are open to the idea and not planning on it, then you may just see how things progress naturally.
It is often a good idea to see your date in their natural habitat. You can learn a lot about them from the way they have decorated and the tidiness on their space. If you rely on your date to describe their home environment it is unlikely that the mental image created will be accurate. Only by seeing their space for yourself can you truly understand important details about them. So if sex is something that you are not ready for you should spell that out upfront, but still accept an invitation to see their space for yourself. By discussing it prior to arrival you can avoid awkward moments later.
