Assuming pregnancy takes place, the only reliable sign that a woman is pregnant is cessation of her menstrual period. If she's late, urine tests are a reliable way to confirm pregnancy, especially if the woman has irregular periods.

Most of the ingredients are about the aggregate state and lubricity of the gel. Any drugs that enhance sexual performances (thanks @...

She had two periods afterwards so she is not pregnant. Who are you to demand that she take a test? You pretty much called her a liar when you did that.

Viagra does not cause a spontaneous erection. You have to be sexually stimulated in order for it to take effect. This particular film scene would suggest that Franco was sexually aroused by the 'chase'. Hope this helps clear things up for you.

Being transgendered is NOT a mental health condition. The American Psychiatric Association states that a mental health disorder requires distress or disability (APA, n.d.). A psychological state is considered a mental disorder only if it causes significant distress or disability. Many transgender people do not experience their gender as distressing or ...

It sounds like you're describing delayed orgasm. I've condensed the relevant bits of the following paper: Jenkins & Mulhall. Delayed orgasm and anorgasmia. Fertility and Sterility, 2015; 104(5):1082-1088. Delayed orgasm/anorgasmia defined as the persistent or recurrent difficulty, delay in, or absence of attaining orgasm after sufficient ...

I generally agree with jj78, although I would add a couple of provisos. a) The answer partly depends on how one defines 'spontaneous', an adjective with more than one meaning: spontaneous adj. 1. occurring, produced, or performed through natural processes without external influence: spontaneous movement. 2. arising from an unforced personal impulse; ...
