First post succesfull,yeehaw!
First issue. I've been having feelings of guilt that the timing has been wrong for them because she is now committed in our relationship even though I am well aware of an attraction between them. My GF is the one to bring it up ( I've been very carefull not to in that respect) but also the first to laugh off the thought when I indicated that the possibilities were not closed from my perspective. For him and her it would be a sensual experience that he at least could most likely use a this point, given the situation. However, he probably wouldnt want anything overly 'serious' at this point. And for that reason I'm okay with it.
For sure I've rationalised the what if's that it may just not end well for everyone but it would sure be nice for some advice. Totally new to this situation
