Particularly tha last paragraph? Should my parent be buying me an expensive purity ring? Without my knowledge. I don't even know if that's what I want to do

I am a 22 year old college student who will be graduating with a bachelors degree in May 2017. While the college years are known to be the wildest times of your life filled with sex, parties, getting drunk and high and more sex - this is not at all how my college years turned out.

I am a virgin- I've never done anything sexual in fact I've actually never been in any type of relationship. Growing up I never made a commitment to stay a virgin it just happened. Most people tell me how great of an accomplishment this is. Don't get me wrong I understand the benefits however I am embarrassed at the fact that I am a 22 year old grown adult and have not been in any relationship. This takes a huge blow at my self esteem as I am always questioning what is so wrong with me that I can't find a guy... ANY GUY that wants my attention. This at times has cause me to feel depressed. I began to question my body, my looks, my personality... All in an effort to figure out why I am alone and still a virgin. :(

I recently find out that my parents are so planning on buying me a purity ring for my Christmas present! What kind of gift is that? I'm not a 12 year old girl who can be bribed into staying away from boys. I'm a women whose capable of making her own decisions and who is frankly sexually frustrated. I do not think its there place to make this type of decisions for me. If or when my relationship with God grows and I decide that I want a purity ring I will do so myself. Is this selfish of me!?
