"It's my first time showing interest in a male. Especially a dog." Yeah, I'm not believing this. You don't like guys, you don't like dogs, your face and body language clearly say you don't want to be here, you're not sharing any dialogue with him or even LOOKING at him... I'm not buying that you would just THROW yourself at this guy, especially if he's feeling as awkward about getting hard as you are about being here at all. He suddenly wants to bail out, and you want to take him up on that offer.
