Regarding foreplay, ejaculating vaginally every time, anal sex etc … I bugged the stew out of our priest about this at our pre-marriage counseling session recently. Here is what we came up with:
Procreative: This is a mental concern almost more than it is physical. You have to look at the mindset of each embrace. For example, are we engaging in oral sex to avoid pregnancy, or is it foreplay? If it is foreplay, then it’s not contraceptive in nature. ** If during a night I engage my husband in oral sex to completion and ALSO have vaginal sex to completion, I am being just as procreative as if it ended vaginally both times. The ejaculation outside does not negate the seed that made it inside … and it’s unlikely I’ve change my procreative mindset during the events of the night. You don’t have to have
more** seed to be procreative … one shot works just fine. As long as it ends
at least once vaginally during the night, then you are obviously open to life the whole time.
For some of the more traditional, sexually conservative couples this may seem pointless as to why you’d want to end it anywhere else … but not all of us feel the same way. As far as anal sex goes, some couples really enjoy it, again it’s up to the couple to decide what’s unitive and what’s not. The point has been brought up in other posts about the health risks involved, which takes me right back to the procreative mindset question - if a couple engages in anal sex with a condom (eliminating the cleanliness issue) and later removes it for vaginal sex with full gift of seed, they were not in a contraceptive mindset. In this case, the condom is a sanitary device, and not a barrier to life.
The simple synopsis: if seed makes it in the right place at some point, you’re open to life. Once the seed ends up where its supposed to, then sticking things in weird places doesn’t reverse that.
