Hi. My girlfriend and I are in a bit of a pickle, except not really. You see, I have no problem making advances toward her and maintaining my being aroused. The problem is that when she makes sexual advances toward me, I get almost completely turned off, and sometimes even upset. I have bipolar disorder and I'm wondering if that may have something to do with my problem, but I don't know. Is there anything that can explain why I can't get turned on by my girlfriend?
