Natalie is probably the best provider for what you are looking for. Check her reviews.  She has had a recent one. Note that she no longer does outcall.

Any recommendations for a good erotic massage provider in the Boston area. Mutual touching, highly erotic. I'm less concerned with drop dead looks and more quality of the provider.

Thanks in advance.

I agree. Natalie is great. Very nice person and excellent erotic massage.

I've been a regular of Natalies for 4-5 years, none better.
