This usually doesn’t happen with women, even if they reach orgasm. Women stay semi-sexually aroused and they love to indulge after-play like post-sex cuddling, love and conversation. As women have less muscle mass, they don’t feel so lethargic after sex.

During sexual acts, the body releases oxytocin hormone. This makes you feel relaxed as it reduces anxiety and stressful thoughts. This also makes it easier for men to sleep afterwards.
