Sex between an adult and a child is automatically rape in this country, consensual or not. In many US states, 'incestuous rape' is a subset of 'rape' and requires tougher sentencing.
And that's as it should be - but incest often takes place not just as adults. Vis a vis adult & minor relations, there've been plenty of older women knocked up by minors in the UK - no one jailed, but the child forced to pay support.
DW - the morning after pill is pretty cheap, & up to 13 weeks any abortion is still cheap - $350! They could do community work ffs as payment instead! A woman's right to choose, but a woman's responsibility for her choice. I'd never suggest minors pay though.
