I found a great resource on ttc that I thought I'd share. I paste a link and one section below on the frequency of intercourse. Its best to seek medical advice than ask peers when it comes to some things like whether drinking is okay while ttc, etc. (You shouldn't at all if you think you might be pregnant - even at 1 DPO!).

Frequency of intercourse

In some cases, clinicians may need to explain the basics of the reproductive process. Information has emerged over the last decade that, at least in theory, may help to define an optimal frequency of intercourse. Whereas abstinence intervals greater than 5 days may adversely affect sperm counts, abstinence intervals as short as 2 days are associated with normal sperm densities (7). A widely held misperception is that frequent ejaculations decrease male fertility. A retrospective study that analyzed almost 10,000 semen specimens observed that, in men with normal semen quality, sperm concentrations and motility remain normal, even with daily ejaculation (8). Surprisingly, in men with oligozoospermia, sperm concentration and motility may be highest with daily ejaculation (8). Abstinence intervals generally also do not appear to affect sperm morphology, as judged by ‘‘strict’’ criteria (9). However, after longer abstinence intervals of 10 days or more, semen parameters begin to deteriorate. Although studies of semen parameters provide useful quantitative data, those data may not accurately predict the functional integrity or capacity of sperm.

Although evidence suggests that daily intercourse may confer a slight advantage, specific recommendations regarding the frequency of intercourse may unnecessarily induce stress. In one study involving 221 presumably fertile couples planning to conceive, the highest cycle fecundability (37% per cycle) was associated with daily intercourse (10). Intercourse on alternate days yielded a comparable pregnancy rate per cycle (33%), but the likelihood for success decreased to 15% per cycle when intercourse occurred only once weekly (10). The stress associated with trying to conceive can reduce sexual esteem, satisfaction, and the frequency of intercourse. These parameters are further aggravated when the timing of intercourse is linked to ovulation predictor methods or follows a strict schedule (11, 12). Couples should be informed that reproductive efficiency increases with the frequency of intercourse and is highest when intercourse occurs every 1 to 2 days, but be advised that the optimal frequency of intercourse is best defined by their own preference within that context.
