Does my boyfriend think I'm a lesbian?

My boyfriend keeps telling me he is super-jealous of my relationship with my best friend. When ever he kisses me or hooks up with me, he always says things like 'Bet you your best friend couldn't make you feel this good' or 'she better not touch you the way I do'. The other day when I hugged my best friend in front of him , after she left, he grabbed me and said he was really jealous and that he could hold me better than she ever could. Should I be worried? Does he think I'm a lesbian? Or could it be something else? by the way, I am not lesbian, I am completly straight. Though I am a huggy person.
