I think my girlfriend is emasculating me and how do I tell her?

My girlfriend is very loving and kind. She has some particular ways that make me feel like she is trying to cut off my danglies. It started by her suggesting we watch girlie stuff together such as Real Housewives, Bridezilla and Lifetime movies, then going to Operas and Ballets, and even to her asking me to hold her purse in the mail while she shops for new outfits. She use to ask to pay for stuff, now its just umed that I pay for everything. I feel like she is either consciously or subconsciously trying to emasculate me. I have a hard time saying "no" to this woman, how can I possibly tell her about what she is doing to by manhood?
