What proportion of acquaintance rapes occur both when (i) it is the
first sexual encounter between these two particular people and (ii) no
condom is used?  Or if this is not available information on the
proportion of acquaintance rapes that occur when it is the first
sexual encounter between these two particular people.  Or the
proportion of acquantiance rapes that occur when no condom is used. 
I'm hoping to find citations to support the answer.

Gatesman,

Are you looking for one statistic of:

     The proportion of acquaintance rapes where
     it is the first sexual encounter between
     the two people AND no condom is used?

Or, are you looking for

     The proportion of acquaintance rapes where
     it is the first sexual encounter between
     these two particular people.

     AND

     The proportion of acquaintance rapes where
     no condom is used.


Please confirm. Thank you.

I'm currently looking through stats for this question.

I haven't yet found a specific stat for "first sexual encounter," but
I have found a category of acquaintance rape called "intimate" defined
as a current or former spouse, boyfriend, or girlfriend. Would this
category satisfy your requirements?

Ideally I would like to know:  the first alternative asked -- The
proportion of acquaintance rapes where it is the first sexual
encounter between
     the two people AND no condom is used? 

But if that is not available information on the separate parts would
be valuable.

Statistics about non-intimate acquaintence rape would be a valuable
proxy for "first sexual encounter".

By the way, I would gladly provide a similar price ($30) if you could
alternatively find out The proportion of sexually transmitted diseases
that are contracted when it is the first sexual encounter between
     the two people AND no condom is used?

With regard to STD's it seems that we should be able to divide the
universe of infections (totaling 100%)into 4 categories... % from
first encounter sex without condom; % from first encounter sex with
condom; % from subsequent encounter sex without condom; % from
subsequent encounter sex with condom.

I would imagine that the percentage from sex with condom is much
smaller than % from first and third categories... but trying to find
this kind of break down would be very helpful
