In the past 60 years of space exploration, we’ve launched satellites, probes, and people into space. Some of them got back, some of them still float through the solar system (and almost beyond it), and many transmit amazing images to our receivers on Earth. In all of these photos, the Earth is (wait for it) spherical. The curvature of the Earth is also visible in the many , many , many , many photos snapped by astronauts aboard the International Space Station. You can see a recent example from ISS Commander Scott Kelly 's Instagram right here:
If you want my strict opinion, I think it’s a poor decision to choose to wait. There is a lot about yourself, sexually, that you simply aren’t going to know until you’ve experienced it, and that knowledge is going to affect your relationship with your partner or partners. Neither will waiting until marriage ensure that this will be your only partner. You can’t divorce-proof your relationship by waiting, nor does having sex before marriage (or engagement, for that matter) doom things. Plus: waiting until after your break-up requires lawyers is a bad time to find out that the two of you don’t sync sexually.
