I have cum inside the woman I am with well over 99% of the time. In previous relationships, or hookups, condoms were used, and the women had no real interest in having me cum anywhere else but deep inside them. On very rare occasions, I have cum inside when the woman was not on birth control and I wasn't wearing on condom. Most of those rare times, she said she was at a 'safe' part of her cycle, and lust got the better of me. Another time was with a pregnant FWB (not by me). She wanted sex with me and assured me she was tested and disease free, so I went for it. These days I always cum deep inside my wife, no condoms, as it is safe to do so.
