Ok so Im slightly on the adventurous side but my bf doesnt seem to be? I can't get too detailed here so email if you want more info. Basically I have offered up a couple things I assumed all guys love and well.....he seemed to send mixed signals and I got 3 really diff excusses as to why he wouldnt be interested not one seemed the real reason....guys help....oh btw we are 25+
