1. First time you have sex. Becky Barnicoat / BuzzFeed You don't know which buttons to push yet – you're a bit self-conscious. First-time sex is clunkier, chafier, and slightly more awkward than you imagined. 2. First outdoor sex. Becky Barnicoat / BuzzFeed Extra spicy if an elderly couple with Nordic walking poles stumble across you midway through. 3. First time you try a really weird position. Becky Barnicoat / BuzzFeed Often also the last time you try that really weird position. 4. First time you have failed sex. Becky Barnicoat / BuzzFeed Maybe you're tired, maybe you're drunk, maybe you're high – for whatever reason, at some point you're forced to conclude that this sex is not going to...well, conclude. 5. First sex in an ~unusual~ place. Becky Barnicoat / BuzzFeed So maybe joining the Mile High Club is too much to ask on EasyJet when there's only one toilet and EVERYONE WOULD SEE AND HEAR YOU. But there are plenty more places to tick off your list – like the disabled toilet in the shop. Hot. 6. First quickie. Becky Barnicoat / BuzzFeed Very fun, but trying to pull yourself out of the post-fuck napping phase to shower and get dressed in time is incredibly difficult. 7. First time you have sex in their childhood bedroom. Becky Barnicoat / BuzzFeed If you're lucky it's been given a beige makeover and turned into the guest room. If you're not, just try not to make eye contact with "Teddy". 8. First time you try the sex position you know is going to be a keeper. Becky Barnicoat / BuzzFeed Neither of you is horribly uncomfortable, and several hands are free for extra duties. Result. 9. First time you realise you haven't bothered with another sex position for a while. Becky Barnicoat / BuzzFeed Some things just don't get boring, and a brilliant sex position with the person you love is one of them.
