Traveling to England and London in a month. Since I have an international phone number, I have instead tried to email numerous erotic massage parlours, but all of them have invalid email addresses (except two with still no reply after a week). 

Is there something I am missing? Is there a way around without calling? Are these webpages simply fake?

You're into massage only if i understood right. If they don't respond to your emails maybe try texting them via telegram or whatsapp.

If you are looking for something more than a massage, here is a list of London Agencies, contact them...

Thanks. Definitely looking for more. Eager to try lingham, preferably with an add-on or two. 

Some good looking masseuses are working there, don't be pushy just let them do their job, you'll be asked a few minutes after the start for some extra massage.

Here's a quick example. They offer full service. Sent an email a week ago without any reply. Is this legit or just bogus?

Very professional tantric massage with Cleo, at The Rub tantric. Not the regular escort massage type, the one that you know is exactly what you have payed for! I felt rubbed many times when I arrived in escort places where there was no clean towels, shower and not a tantric massage at all, call it handjob, but not tantric.

You're reffering to this massage parlour, right?
