Too much sex in our relationship - is that normal ?

How much is too much? And what does it matter what's considered normal? If it's more than you want, it's too much; if you enjoy it, it's the right amount, and it's normal. It's hard to know from what you write if you are asking because you think there is a "normal" acceptable amount of sex to have, and you think you are exceeding this quota. If that's the case, there is no "normal" except what makes both people happy, so stop worrying and enjoy it. If, however, you are asking because you feel he is asking for more sex than you want, then it's not "normal". Is it that you think he only likes sex, and isn't fussy about who he's having it with? Do you think he is trying to prove something through so much sex? I think you need to work out what exactly is making you uncomfortable about all the sex, and communicate that to your boyfriend. You say he was accepting when you turned down sex before, so it sounds as if he is willing to modify his demands if they are higher than yours, or to give you reassurance about his intentions if that's what you need.
