I don't think it's silly at all - I don't like visiting private homes, lots of ladies only do outcalls to hotels, and (particularly if you're new) there are a lot of very good reasons not to - you don't know the layout, where the exits are or whether they are locked, you have no way of knowing who else might be in the premises or have access and let themselves in whilst you're there and there's unlikely to be uninvolved people within earshot who will be able to hear you if you need to raise the alarm. Plus the state of the bathrooms can be nothing short of traumatising
.
If you're doing outcalls, it's up to the punter to arrange the venue and you need to carry out your security checks to make sure he's actually there and hopefully avoid wild goose chases (nothing's foolproof, and if he's pulled/pissed/asleep when you arrive you can't make him open the door if he doesn't want to, but it doesn't happen that often and it's never happened to me
). However you can also book a day room somewhere for your own use and offer incall days if you want to dip your toe in the water - lots of ladies without an incall base do this rather than full on touring, and if you find you're getting asked a lot for incalls it's worth a try as well.
