What Does a Healthy Sex Life Look Like in Marriage?

Noa T says hard to find people to answer these awkward questions what does a healthy sex life look like in marriage. How often when spicing things up etc how do you combat last when does it become lustful sorry if this is too personal the question let me try to set the grounding for this. So Thomas Aquinas says that there are two ends he actually points to this in marriage the marital act right? "I know this is a difficult line for people to accept today because of how men in particular seem to have abused their sexuality in relationship to women"
