No, not every provider offers 90 minutes.  If she doesnt have a certain time period listed on her site (such as 30 min, 1 hour, 90 minutes, etc), more than likely she does not offer it.

It doesnt hurt to ask someone you've seen several times and have built a rapport with, if she'll see you for an unlisted amount of time, but chances are, she'll say no, preferring to only to see those who will see her for her time minimum.  

i love sex, intimacy and good convo...stay a lil longer and I don't charge extra because u r cool

Why not just ask for a 90 minute session? I certainly wouldn't have any problem offering it if a client requested it.

You might have to work with what they have..... I have 90 mins available but since many of your to-do's don't I suggest you work with an hr our 2 hrs OR contact them and ask is a 90 min session possible.

That's a good question. I believe I have it on my site...however, I thought most provider's offered it but may not quote it for whatever reason. Because typically half or full hour's are more requested.

offer 90 minutes and it is not listed.Currently,it is not listed on my website,but I think I might start offering  90min escapades as I like to call them.So you never know unless you ask you might be pleasantly surprised.

occurred to me until I started getting requests for them, after which I put the rate up on my site. Just ask. If a lady offers one hour and two hour sessions, I see little reason for her not to go for an hour and a half (not every lady, but you know). I tend to like one and a half hours too, for the reasons you stated.

Although I don't advertise it on my site. I would suggest asking regardless of whether or not it is posted on her site. The worst thing she could say is no.
