17 & 15?

my boyfriend is 15 (16 in April) and I'm 17. we have been dating for 13 months and "talking" for 3 years. I just recently got on the pill. the age thing isn't weird for us because it's kind of a trend in his family for the woman to be older. we have been talking about starting to have sex. at first we didn't want to because well we just didn't idk? and lately he's been getting jealous because I'm not a virgin and he is. I love sex so I would want this. he says he does but I don't really know. anyway, does the age thing seem bad???
