sure, but only if what you're looking for is an experience with a woman who views what she does as receiving money in exchange for allowing you to spend time fucking the agreed upon orifices. If so consider buying a realdoll.. it's a solid investment in never getting the bait and switch, not having to worry about being seen visiting an sp, and msog until the cows come home (cleanup is a cinch with a detachable shower head)
If you want a seductive, passionate, exciting woman to really turn you on and enjoy the hell out of you, do the research, check her photos, reviews, webcopy, and contact requirements (does she need referrals, will you be comfortable giving her the information she will want from you for security) and then make contact. If her msog policy is one that leaves your second goal at her discretion and you are worried she is going to be trying to rush you or demand money midsession for a second shot, just ask her in plain english about it and see how she answers. It is a lot nicer to hear an escort tell you that her msog policy isn't going to apply to you than the other way around. If a client is oblivious to the further discomfort, erectile issues, or possibility of succesfully having sex again, showering, getting dressed, and being out the door in the seven remaining minutes before their time is up... it isn't easy to say "msog is great, so long as you aren't hurting me, totally oblivious to your limitations, or just being unreasonable" in a way that will suit a mans ego.
Fact is, while some people are freakish prudes.. most of the top end escorts here in Van. are motivated in part by a love of sex, and why the hell would anyone say no to good sex twice if they had the time?
