To be fair it doesn't matter if she was happy to have it before. Nobody is entitled to sex and nobody should be pressured, forced or coerced. No means no.So basically he wants sex and she doesn't, I get that but she was happy to do it to get pregnant again, or is she saying thats how she got pregnant by pressure?
Pregnancy hormones are horrible and if she doesn't feel like having sex then tough shit, he's got 2 hands.
