Finishing?

So my bf and I of 3+ years been sexually active the last few months since our anniversary in November. We don’t get the chance to do it often but when we do (sleepovers) we usually go a few rounds.

We’ve been using condoms, I’m not on the pill (in the process of getting it) and whenever he’s close we pull out and I’ll give him head until he finishes.

Has anyone ever had experience of having someone cum in the condom? Would you recommend/how “safe” would you say having your man orgasm in the condom is?

We’re also each other’s firsts, so no prior STDs etc :)
