So close... again

I was at work thinking about Gavin and sex and asking myself when there would be the chance to have sex? I was somehow communicating with him (messaging, chatting, looking at each other?). Gavin was married or engaged, every now and then he had a gold ring on his ringfinger. Then me and, Gavin and this other guy went to lunch. We had agreed on having sex during the lunch break so no now would wonder how we're away at the same time. We could not just skip so we had to ask that older guy for some advice. Gavin asked the guy "If we were about to have sex now, do you think it's a good idea? You've been there so you know.". The older guy said it's up to us and he won't tell anyone though. So we skipped. We were just walking and talking, mostly this and that and where we should do it. Then we were by the sea, in the woods. I had to go to the toilet and found this one pretty ok one. Gavin asked if we should go to the ones with the blue doors to have sex, but I went in to another toilet since I didn't really want to do it in a public toilet and hoped he didn't find me. Then when I saw Gavin, he was my old friend "Thomas" (who I haven't seen in 2-3 years). He kissed me and it was like we were supposed to have sex. I didn't want to. The next thing I remember is that we were in some apartment and I just woke up. I had sleepy hair and luckily all my clothes still on. I looked around, saw Thomas in another room and though "Oh no I need to get back to work, I've been gone 4h, what's Gavin gonna think?". Then I got up, talked to Thomas, or just told him I have to go and pretty much ditched him. When I got to work I looked like I'd been sleeping or having sex. I was look at Gavin and he didn't really notice me, except that he looked like he was thinking I'd slept with someone else during the time I was away. Then Gavin and I started messaging on WhatsApp and talking about doing it, how I felt about all this "almost doing it" and that I can't taking it anymore, and about what we'd do to each other. Then he said we'd do it today or tomorrow (?) and this time for real and no postponing no matter what.
