Hi Rosaley,
I'm very conscious of my safety too, being a young woman visiting strangers' homes/hotel rooms is dangerous but you can minimise the risks and I've never had any dangerous encounters in 2 years of doing outcalls only (I see a few men every week).
The chances of being booked by a group of men who want to gang rape you are actually very small and those men will target vulnerable ladies. Make it clear on your advertising that you have a security buddy/guard (you don't have to say it's your husband) and if you visit a house then get full address and ask to call their landline so you can check you live there and speak on the phone to them. This will put off a lot of sketchy types.
In a hotel room it is very unlikely due to other people being able to hear and the hotel would notice a group of men going into 1 room. (Definitely invest in a rape alarm if you can, it helps me feel more prepared in case of needing to get attention fast).
When you arrive get your fee, then make the call to your husband "security buddy" and tell him out loud 'I have arrived at [location] and will be leaving at [time], please call me back then'. If they know someone knows where you are and is expecting to hear from you at a certain time, you'll put off any bad behaviour/boundary pushing.
The majority of punters are just normal guys who want some sex and company, only a very small amount are dangerous and will be unlikely to target someone who carries out security procedures rigorously.
I have never been in a relationship where my escorting was a joint decision, I don't want to be patronising but please always make your own decisions about who you see/what you do and when you see them.
It's perfectly safe to do incalls without someone else there if your hubby can't be there, just make sure you speak to them over the phone and don't give out your address until the punter has arrived at somewhere close to yours, otherwise all sorts of idiots will get your address then start turning up randomly.
Loads of great information and guides on the main site and on old threads here, I've learnt most of what I know through SAAFE
