at 1st she wants relationship wit no strings attarch,2nd she wanted unprotected sex,3rd she dispose the used condoms herself.she might be a married woman that her husband has problem in impregenating her and she needs a child your friend might be doing her a big favour.
I guess so, but all that was confusing was this, at first she told the guy that she is single and do not intend to build up any relationships with anyone.
she does'nt want your friend to claim the child or blackmail her in future(maybe)
