A note from old Trans* Granny here, but in case it rains while you are making love make sure HE puts his rubbers on or he will get cold.
Most rubbers (condoms) come with a fair amount of lubrication on them to make life nice for both parties lube wise. (We CAN get STD's and AIDS through vaginal or backdoor intercourse too.) The image you are cis-would be highly improved by taking the precautions, and if you are younger, there are Contraceptive gels and foams that will not hurt us internally, but which are put in by using injection tubes, which can be used in foreplay, some products even taste good if he likes that sort of thing.
I do self lubricate to the point that a condom that was fresh from its container would give "him" enough time to finish his job and I am "post menopausal" age wise but still on HRT. At every Pride event I went to, there were several booths from Pleasure Lubricant merchants, and some claimed to be both super slippery, and some gave a variety of sensations. I actually tried a couple of samples during my dilation sessions, and they were not bad. Do not use that kind of stuff in the first year Post though, unless an OB/GYN gives you a green light.
