I dont know if I just i had an ?

see I'm not a virgin but I am sooooo scared of getting diseases or getting pregnant that I decided to try my hardest to stop hooking up with guys. The thing is I've never had an before and I've always wanted to have one. So I bought a vibrator lol. I tried it for the first time today and I think it worked. (I think) All I know is that I was using it for a couple of minutes and then I started to get this really INTENSE feeling in my groin. But it was weird. Like say you're feet are really ticklish... imagine someone tickling your feet and they DONT STOP. It felt like that only more intense. Its like I wanted it to stop but at the same time I wanted it to go on forever and ever... did I have an ? and more importantly does the fact that it wasn't good or bad just INTENSE normal?
