Am I a slut for doing this? ?

Okay well me and this guy met at a wedding and we got along really well so I added him on fb and I we start talking and we went out on a date but he is 24 and I am 18. But I kinda like him. And we were cuddling in his car for a long time. We were texting the other day and he was like send me a sexxy pic and j was like how sexy do u want it and he said suprise me so I just sent a pic with my boobs only and than I asked him if he had ever went down on a girl and he said yes and I was like can u go down on me and he was like sure so I sent him a pic of my pussy and my pussy opened up. He said he got really horny cuz I have a tight and pretty pussy. So basically me and this guy r gonna meet up and do oral and 69 when I have only hung out with him twice do u think I am a whore for doing this? And is he too old for me
