I wouldn't call it a 'fetish' but ......
I never wear a condom, only going with women that I've known for quiet some time and who I know are 'clean'.
I always ascertain that they are 'safe' - on the pill/IUD/sterilized - because at the start of fucking/love making neither I, nor, with a few exception, them want to be made pregnant.
But
When my 'point of no return' is reached, when my cock makes its final growth and I feel the cum pushing up my shaft I try to plant 'my seed' as deep as possible, in that split second instinctively trying to impregnate them.
All my partners have also at their 'point(s) of no return' wanted/ urged and aided me to cum that way.
The few exceptions have been married women, who I found out after the acts, had been trying unsuccessfully, combined with no sexual satisfaction, to get pregnant ...... luckily, whilst all indications were that they got the sought for satisfaction (not boasting), as far as I know, despite my 'deep planting' I didn't make them pregnant.
I don't get any satisfaction from cumming anywhere other than deep in a pussy and that includes from masturbation which is more for 'relief' than satisfaction.
A few times, when asked to, I have cum on a partner's tits and one partner, when she was in the first part of her period, liked me to cum on her clit.
I have never cum on a partner's face and never in a partner's mouth.
This maybe going 'off track' and the source of another thread - but all my partners have had a 'fascination' with cum, at some stage of the 'relationship' wanting to see me cum ...... one even before our 'first bout', telling me afterwards that "although she definitely didn't want to get pregnant and was on the pill, if I hadn't powerfully and copiously produced we wouldn't have had sex".
