Roma 1:26

1:26 For this reason God gave them over to dishonorable passions. For their women exchanged the natural sexual relations for unnatural ones, ¹ 

Roma 8:5

8:5 For those who live according to the flesh have their outlook shaped by ²  the things of the flesh, but those who live according to the Spirit have their outlook shaped by the things of the Spirit.

[1:26]  ¹ tn Grk “for their females exchanged the natural function for that which is contrary to nature.” The term χρῆσις (crhsi") has the force of “sexual relations” here (L&N 23.65).

[8:5]  ² tn Grk “think on” or “are intent on” (twice in this verse). What is in view here is not primarily preoccupation, however, but worldview. Translations like “set their mind on” could be misunderstood by the typical English reader to refer exclusively to preoccupation.
