Steppin' up the Sexy

So recently I learned about one of my friend's new addictions... lingerie shopping. Apparently she has been feeling the need since she started seeing "someone" on a regular basis. For those of you who have been to Vicki's lately you know the sexy under garmets do not come cheap (but they do cum easy!!). So my girl has been spending a ridiculous amount of money on sexy lingerie... so what?? She can have a different look each night. This is where I say waste of money and time!! The last lingerie I bought for my man was for his birthday. It took me about 20 minutes to get into it and it took him about 2 minutes to get me out. Don't get me wrong, he was very appreciative, but it was for his birthday. I'm not pulling that shit on a daily... or every other day.. or even once a week basis. And so far, it hasn't stopped my man from trying to get a piece every chance he can get. In fact, he has told me my regular pj's (my dad's old football jersey) is sexy. He looks forward to seeing me in it. I'm not saying we don't ever whip out some new lingerie... we don't ever go the extra mile to make sure our man is super turned on. But in the 8 months that I have had a boyfriend, I have pulled out the lingerie once. It was an $80 bill... that's 10 bucks a month... so I'm pretty pleased with the stripper-like attire I have purchased for my man. Maybe I'm totally wrong... am I lacking in the "sexy department" because I don't break out the lingerie on a regualar basis? Is this a part of my game I need to step up?? I'm open to all opinions on the matter...
