I use condoms when having sex with people for the first time or with people I don’t know that well. I have the implant, so if a regular sexual relationship develops with someone and I feel comfortable and like I can trust them, I don’t feel the need to use a condom. Sex is noticeably a lot more comfortable for me without one. I would feel awkward asking someon when they were last checked for STI’s if I didn’t know them that well. 

In terms of buying, I usually pick them up from clinics and stuff where they hand them out for free. I always have some spare in my room, but don’t carry them about with me. If I was at someone else’s house I would expect them to have condoms I think. There have been times when they haven’t, so we’ve not had sex.
