Newbie P411 question

I recently signed up at P411, and I have a quick question. Is it acceptable to inquire about services in their private message system? MSOG is a necessity for me, and I want to make sure it is available, but I don't want to violate any type of protocol. If it's not mentioned in their ad, what is the best way to ask?

Check their reviews! Most of them will tell you!

Well that just makes too much sense, lol. Of course I miss the obvious answer...Thanks!

If their reviews arent fruitful, after screening you could always just ask. Pending you cant find the info.

You can state in your profile you prefer MSOG. Some girls will check your profile when you contact them.

Reviews and posts are a good way to see what's offered. I like to check the posts of gentlemen who inquire, and I think its a good idea for them to do the same. Although, I can't say I would be offended if someone asked me whether MSOG were available. Its a good idea to wait until after screening, but you should be able to ask at that point.
