D. Sharing needles

Explanation:

Sharing a needle or syringe to inject any substance (including steroids, hormones or silicone) puts you at risk of HIV and other infections found in the blood, like hepatitis C. You’re at risk whether you’re injecting under the skin only or directly into your bloodstream.

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
