I am perfectly content with 1SOG per session, for me its all about the experience. Getting to know the person i am with, chatting, laughing, and lots of foreplay and never forget the intimacy aspect.
90 minute sessions are just perfect most times to achieve this, and with certain individuals, i want 2 to 3 hours, simply because i really enjoy the company and the foreplay is out of this world. And of course on these extended sessions, i go for 2 SOG and if all goes well, maybe 3, but i don't force it.
Otherwise, I spread my hours through out the day and visit 2 or 3 different ladies. I have also started with one lady in the morning and revisited her later in the day to finish up my hat rick for the day.
Happy orgasms to everyone. And multiples for you ladies.
