Welcome First time. All good advice above. However, visiting an escort in her apartment isn't such a bad thing. I was very wary at first too. But i think most of the girls on this site prefer in-calls (in her place) vs outcalls (your place). Chatting to some escorts i've seen, this is because of safety, especially when they are seeing you for the first time. Also an escort will be more comfaortable and familiar in her own environment and this will have a positive knock on effect on you.
What are your concerns about seeing an escort in her apartment (as opposed to getting an outcall, which incidentally is more expensive, and will probaly have a minimum time requirement)?
