Driving down the 404 eh, well, there's a prime situation for a rollover.
Women often will pull this little trick, so you have to be prepared for it when it comes. Try, "you know honey, i would but you are just too much woman for me now"
As far as the disease thing goes, have you ever had any symptoms?
In 91, my ex from University and I got together again for another short but sweet relationship. At the time, she told me that i had given her Chlamydia (spelling) when we were together in University.
Seeing as each of us had only slept with one other person prior to our relationship, i was blown away. I never had any symptoms. She said she didn't blame me, because i probably didn't know i had it.
I still couldn't believe it, but the next day, i went to the STD clinic at Toronto General. The doctor there was slightly amused at my tale and assured me that 95% of the time, males will exhibit symptoms, and that if i had been carrying Chlamydia for all those years, i would have been in pretty bad shape.
Never the less, he gave me the Q tip up the end of the knob treatment.
Not pleasant at all, i much prefered the ultra sound on my balls.
Anyway, it was negative.
I had a great sense of joy when i told my ex that she may have had chlamydia, but she didn't get it from me.
Still if you are edgy about it, why not get a series of tests done to find out for yourself.
The other thing to consider is that women are hardly saints either (except your wife, she is without a doubt faithfull to the core).
You can BET on the following:
It's going to come up again, and probably sooner rather than later, she suspects something.
So you'd better get your ass tested, and work on your presentation.
