I sometimes wonder, if the adding of pregnancy content increases or decreases the potential audience. The people begging for this content sure make it look, like it is super popular. But I think this is a distored statistic. They beg for it, because it is unpopular fetish.
For me, pregnancy is a turn off. A big one. It puts realism in a light hearted lewd game. What next? No anal anymore, because they did not clean their rear entry preemtively? Also, if pregnancy is possible, the characters would know this and not have casual sex all the time without condoms!
I say, if you ad impreg, you should add condoms. And remove the anal content. Also characters should talk about birth control a lot more.
