Herpes Scare

I am a male and had a unprotected vaginal sex 7 days
ago with someone I didn't know very well, additional I
performed a small amount of oral sex-but saw no
visible signs of anything. The day following the
exposure I had an abrasive masturbation session. The
next day I felt a generalized burning sensation all
over my genitals, but mostly at the tip of my penis
and a bit on my testicles. I also had an odd burning
on my left foot(hopefully this is all just anxiety)
But the anxiety is through the roof- I check for
symptoms 30 times a day. The Burning sensation has
lasted 6 days from exposure and is somewhat
fading...... I look at my penis and can see small
bumps that could be anything - there is no overt
redness and no obvious irrations-but little bumps seem
to come and go as I stretch the skin. ON day six i
developed a cold sore(I get cold sores maybe once a
year during stress) and this time the cold sore
appeared on both upper and lower lip - but not all
that bad....I went to see my doctor on day five for a
respiratory tract infection, I told her what happened
and she did a chlamydia and syphilis test but said
Herpes test this early would not help without visible
lesions-she saw none. I intend to go back for HIV and
Herp blood test at the appropriate time... during
this six day period I have had terrible anxiety -no
sleep in a day and a half and not eating! My
questions are:

1) if I developed a cold sore on my face is that
indicative anything other than stress-from oral?

2) additionally, if the cold sore(HSV1) appeared
wouldn't HSV2 also appear and is it a good sing that
the HSV1 came and no HSV2 symptoms(as no visible
lesions and the burning is subsiding mostly at day
7-almost)

3) or is all a crap shoot and I should be expecting
something to happen soon?

4) Finally- If my HSV1 provides some protection
against HSV2 symptoms could the be so minor that
although I have HSV2 I have no visible lesions

Last question-sorry - IF I test positive for HSV2 is
it possible that THE COLD SORES ARE hsv 2 AND not HSV1
and is it really all that helpful if the test cannot
determine the actual location of the virus?

THank you very much
