Prevention of Insanity

So, I asked my older sister to help me get birth control. She doesn't know my sensual my side all that well. I choose not to tell my family a lot. However, she was cool with it. I suggested the pill. She suggested the shot or an IUD. If you aren't familiar with and IUD, one example is Mirena. It's a T-shaped device that's inserted. I'm not exactly sure how it works, but it's 99.9% effective for 5 years at preventing pregnancy.
I'm not sure which one we'll end up going on, but I'm glad she's cool with it. Even though I lied to her as to why I wanted it. My excuse was rape. I've told my family that I'm celibate, planning to never get married or have sex. I really don't plan on getting married. I don't think it's for me. However, sex is a different subject. I'm pretty sure my sister knows that I'm interested in sex and having it, but she's also ok with me not telling her the whole truth, because it's my choice not to. I will tell her eventually how things went down. Probably around Thanksgiving or some time when I get home from college, some time after losing my virginity and after I let my relationship with Scott develop a bit.
Oh and on the way home, we found this store called the Velvet Box, I think, and she said "Well we can't just walk in, look around and not buy anything." I looked at her and said, "Yes we can." In response, she said "Ok," U-turned and parked. I couldn't help but laugh at her. We walked in, saw a lot of lingerie and I thought they were adorable, however a guy would probably think sexy. I wanted to buy one because I had the money. As you go farther in the story, you'll find vibrators, dildos, lube and other things of the sort. It was my first time in a store of that type and I found it fascinating. My sister also felt rather normal about it. I texted Scott telling him I was in a sex store with my sister. He responded "Zomg!!" I laughed. Honestly, those dildos were scary. A bit too long and a bit too thick. I'm not exactly sure how big Scott is, he says between 6-7 inches, but that doesn't include thickness. I've seen it over webcam, but it's not quite the same. Anywho, the store was pleasant. I expect to return, but with Scott instead of my sister.
I think it's funny how my posts seem to always turn back to Scott and/or sex. Is that a bad thing? I don't have much of a life so it'll probably be that way for a while. He's leaving for vacation though. I don't plan on texting him, don't want to disrupt his trip. I'll be happy to text him if he texts me though.
