I absolutely adore my boyfriend of now 3 months. I want to be honest with him, but I'm having trouble deciding how to approach the whole SI thing... He's already asked me once about the scars on my thigh, but at the time it caught me so off guard that I just couldn't spit out the truth... I just told him not to worry about it, and he hasn't mentioned it since, but (and here I risk briefly giving a tad too much info...) while kissing, I've noticed once or twice when his hands go up the side of my thigh, his fingers linger on the area of skin harboring the small army of scars; his hands go back over them as if feeling the raised marks on the skin, wondering where they might have come from, but to his credit, he says nothing (he's so damn considerate... god, he makes me melt ^___^). I feel that he knows I'm holding back, and I strongly think he deserves to know this about me; I just don't know how to approach the subject, and I'm worried about how he'll react.

Any advice?
