Came During Foreplay/ Is it normal?!?!?

Jenny

Soooo I came during our foreplay. He barely went down on me and he played with my tits for like 5'. Then I just could not hold it longer so I came. (I think it was because I was so horny at the time...maybe?) He didn't know that I orgasmed so he continuously doing his job u know. I had to stop him and tell him that I just came. (My body becomes very sensitive after I cum) so He laughed and joked about it "wow that was unexpected...lol you are so lame baby" then he kissed me and we had to pause. I felt so bad that we had to pause because of me, and a bit embarrassed tbh. I had to ask him to do it again. I mean to have sex and he was like "are you sure?" We have been having sex for like a year and a half now and everything is great. Except I didn't know how to orgasm or I have never cum until two months ago. When I realize I can easily cum when he plays with my tits. Yes he plays with my tits all the time but not to that point that my clit just tighten up without any contacts. So Am I the only one? Does anyone cum in their fore play as well? I think it's kinda embarrassed to ask but is normal to have orgasms just from having interactions with the tits!!??!?
