is there really such a thing as too much sex?

me and my boyfriend of 3 years (we're both hormonal teenagers) are really sexually active. though it didnt start until 3 months ago when he took my virginity. Ever since then we havent been able to keep our hands off eachother, I thought the activity would calm down after a couple weeks, though we're still pretty intense with eachother. as slutty and guilty as it makes me feel I've lost every virginity to him already.

so i have a couple questions. we're very affectionate and he does practically everything for me but does it seem like our relationship is just sex?

as well as do you think we're moving at too fast of a pace?
