The speaker wants to fall in love, but only a certain kind of love: the gentle kind that would inspire sonnets about joy and warm embraces. They compare it to basking in the sun, something easy and comforting that asks nothing but that you lie back and enjoy it.
The poem turns on the word "because." The wish isn't really a romantic daydream; it comes from exhaustion. The speaker is "tired" of feeling love "like one would feel a storm," which suggests that love for them has meant upheaval, being overwhelmed and battered rather than held. The ellipses make the voice sound weary, as if each admission takes a breath.
The mood is quiet, tender and a little sad. Sun and storm sit side by side as opposites, and the speaker longs for the first while only knowing the second. There's hope in the wanting, but it's the hope of someone who needs rest more than excitement.
