You're doing 'aces' on ALL fronts! From my feminine perspective I see 4 major positives in your recent posts: (1) GF wants to include you in socializing with her work associates, (2) GF wants to work out with you at her health club, (3) GF has been initiating (this means that she has not only been thinking about you but places importance on initiating contact AND feels comfortable enough with you that she is letting down her defenses a bit) AND (4) you are showing self-respect by taking care of yourself. I agree with the other posters that #4 is VERY important for all of us here especially, but also for everyone really for life.
From a woman's perspective when a man respects himself (as long as he is not selfish) he exudes confidence. Confidence and thoughtfulness are very s*xy to most women (remember I said before that women in general seek security). Like Jody always says "a generous spirit is sexy" (my paraphrase of something she says to me a lot). I think generally speaking that women find men to be attractive if they are confident, generous, and thoughtful.
When you take time to take care of your mental and physical health, that sends an unspoken message to a woman that you are not needy. This makes her feel like she won't need to take care of you all the time. That said, I like the idea proposed by Harville Hendrix' IMAGO therapy that in a healthy relationship both people switch back and forth between the roles of caregiver and recipient.
Jody also says that a good belly laugh releases oxytocin, which is a hormone that promotes bonding. It is released after orgasm, but for those of us who don't have that option, here is a suggestion for producing belly laughs that worked fabulously when my H made an unscheduled visit to the house last evening. H came to collect some boxes of his stuff to move into his new house. He invited himself for a beer on the patio (his idea). After listening and validating for a couple hours, ala DB, I remembered that I had bought a new book called "More Adult Mammoth Mad Libs". For those of you who are uninitiated, Mad Libs are a children's word game (Google 'Mad Libs' for more info). Adult Mad Libs are the adult version. You can buy them on amazon.com or Barnes & Noble. The person you are playing with provides parts of speech (noun, verb, adjective, etc.) without knowledge of their context in the story. For the adult version I recommend that you provide creative, spicy, and suggestive words (e.g. sweaty, sticky,.......) as well as unusual words (e.g. hairball, toe nail clippings....you get the idea). When finished you read the completed story to the person who supplied the words. I was able to flirt in a major way with my H by doing this and he was laughing almost as hard as I was. I'm sure he'll be back to 'play' Mad Libs again. This could be a way to spice things up with GF........Just an idea.........
Maybe I'll start my own thread to do group Mad Libs with everyone?????? What do you think?
