When I'm hypomanic, I feel so sexy and love attention, even if it's just someone checking me out at the grocery store. I am tempted to reach out to get attention from other men, but instead I focus on getting attention from my husband, and he never disappoints.

Next time, try to drink less so you will be more under control and direct the attention-getting toward your husband. Buy some sexy lingerie and surprise him with it. Maybe make it a special date night and go to a nice restaurant. Just some ideas.
But yes, being hyper-sexual is normal with mania, but it's good to find a way to channel it in a healthy way. Your husband would probably be upset if he knew about what happened. So see if you can take precautions to prevent the flirting with other men (such as setting a drink limit, having your husband with you, etc.). If you feel like your thoughts and behavior is getting out of control, make an appointment to see your pdoc ASAP. If you don't go sooner, at least make sure your pdoc knows about this the next time you see him/her. Best wishes!!
